anonymous one year ago Charlie's Computer Company charges \$0.65 per pound to ship computers. Part A: Write an equation to determine the total cost, c, to ship p pounds of computers. Use your equation to determine the cost of shipping 2 pounds of computers. (6 points) Part B: If the company reduces the cost to ship computers by 0.05 per pound, write an equation to determine the total cost, c, to ship p pounds of computers with the reduced cost. (4 points)

hint: if one pound costs 0.65 dollars, then p pounds cost: 0.65*p

3. anonymous

are we doing part a?

4. Michele_Laino

yes!

5. anonymous

okay.. 0.65p ?

6. Michele_Laino

correct! $c = 0.65 \cdot p$

7. anonymous

so what do we say for part a?

8. Michele_Laino

we can say this: "the requested equation, is: $$c = 0.65 \cdot p$$"

9. anonymous

ok and part b?

10. Michele_Laino

now, we have to replace p with 2, so we get: $c = 0.65 \cdot p = 0.65 \cdot 2 = ...?$

11. anonymous

i dont know that one :(

12. Michele_Laino

it is simple: c=0.65*2=1.3 dollars

13. anonymous

oh okay.. :)

14. Michele_Laino

for part B) if one pound is shipped for 0.05 dollars, then p pounds are shipped for: 0.05*p

15. anonymous

what do we say for part b?

16. Michele_Laino

we can write this statement: "the cost to ship $$p$$ pounds, with the reduced unitary cost is $$c=0.05 \cdot p$$"

17. anonymous

so whats part A and Part B... please include all of the work :)

18. Michele_Laino

summarizing, we can write this: part A) requested formula is $$c=0.65 \cdot p$$ so, specializing to p=2, we have: $$c=0.65 \cdot 2=1.30$$ part B) the new formula, using the reduced unitary cost, is: $$c=0.05 \cdot p$$

ok thanks :) i have more questions :)

20. Michele_Laino

please wait, since someone has tagged me

okay ;)
