Group Title
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?

a) 7000 = 5x + 7y , where x is digicel and y is lime

i had that for a and i thought mine was wrong, now im understanding :)

it could be 7000 > 5x + 7y

bcuz the 7000 is her budget

so wat about part b and c
 2 years ago

ChmE Group TitleBest ResponseYou've already chosen the best response.1
part 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

part 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

part 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

let me know what you got solving for y or x and I'll check you. You should be fine from there

is it that?

7000 = 5x + 7y 7000  5x = 7y 1000  (5/7)x = y The graph looks correct.

lets change the cost of digicel to 10 for easy math sake

ChmE Group TitleBest ResponseYou've already chosen the best response.1
7000 = 10x + 7y (0,1000) (700,0)

So what do you think the answers are for c

i think that as the cost per minute for digicel increase then the budget line will become steeper, is it?

ChmE Group TitleBest ResponseYou've already chosen the best response.1
Because 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?

ok thanks i knw what u mean but im not sure how to explain it in terms of intercepts.

Look at the lime intercept of the 2 graphs. Do they change? same for the digicel, do they change
 2 years ago

GoldRush18 Group TitleBest ResponseYou've already chosen the best response.1
ok the y axis which is lime does not change but the x axis which is digicel changes when price increase, im trying to answer
 2 years ago

ChmE Group TitleBest ResponseYou've already chosen the best response.1
correct for lime, it stays the same. How does the digicel change
 2 years ago

GoldRush18 Group TitleBest ResponseYou've already chosen the best response.1
the digicel changes because there was an increase in the cost.
 2 years ago

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

ChmE Group TitleBest ResponseYou've already chosen the best response.1
increase of decrease
