Sandra uses two mobile cell phones( a digicel and a lime phone), to make her monthly calls. Sandra budget only $7000 on telephone calls per month and the cost per minute for digicel and lime are $5.00 and $7.00 respectively.
a. Write down the algebraic equation for Sandra's budget constraint.
b. Graph then Sandra's budget constraint. ( the budget constraint intercepts should be shown clearly on the graph)
c. How will an increase in the cost per minute for digicel call affect the budget line's y_intercept, xintercept and the slope?

Best ResponseYou've already chosen the best response.1a) 7000 = 5x + 7y , where x is digicel and y is lime

Best ResponseYou've already chosen the best response.1it could be 7000 > 5x + 7y

Best ResponseYou've already chosen the best response.1because she can't go over but can be under

Best ResponseYou've already chosen the best response.1bcuz the 7000 is her budget

Best ResponseYou've already chosen the best response.1so wat about part b and c

Best ResponseYou've already chosen the best response.1part b is asking for a budget constraint line and part be also said equation for budget restraint. I would put 7000 = 7x + 5y as the answer for part a because that is the restraint line. Something that she can't go over

Best ResponseYou've already chosen the best response.1part b is kinda difficult. You should solve for y so the equation is in y = mx + b form then you can graph it. label your axis according to what cell phone. So if we solve for y, the y axis will be the lime phone

Best ResponseYou've already chosen the best response.1part c I would just pick an increased amount for the cost per minute. graph that as well, and you should easily be able to see the differences from there

Best ResponseYou've already chosen the best response.1let me know what you got solving for y or x and I'll check you. You should be fine from there

Best ResponseYou've already chosen the best response.17000 = 5x + 7y 7000  5x = 7y 1000  (5/7)x = y The graph looks correct.

Best ResponseYou've already chosen the best response.17000 = 10x + 7y (0,1000) (700,0)

Best ResponseYou've already chosen the best response.1So what do you think the answers are for c

Best ResponseYou've already chosen the best response.1i think that as the cost per minute for digicel increase then the budget line will become steeper, is it?

ChmE

Best ResponseYou've already chosen the best response.1Because the x and y can easily be switched between the diff cell phones make sure you are stating your assumption of what x and y are along the way. You shouldn't be wrong because it doesn't say what each should be. That is correct. Technically it gets more negative. laymen's term steeper. What about the intercepts?

Best ResponseYou've already chosen the best response.1ok thanks i knw what u mean but im not sure how to explain it in terms of intercepts.

Best ResponseYou've already chosen the best response.1Look at the lime intercept of the 2 graphs. Do they change? same for the digicel, do they change

Best ResponseYou've already chosen the best response.1ok the y axis which is lime does not change but the x axis which is digicel changes when price increase, im trying to answer

ChmE

Best ResponseYou've already chosen the best response.1correct for lime, it stays the same. How does the digicel change

GoldRush18

Best ResponseYou've already chosen the best response.1the digicel changes because there was an increase in the cost.

ChmE

Best ResponseYou've already chosen the best response.1correct but in what way does it change? That is how you need to answer this question
