Question

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)

Answer 1

Answer 2

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

Answer 3

are we doing part a?

Answer 4

yes!

Answer 5

okay.. 0.65p ?

Answer 6

correct!
\[c = 0.65 \cdot p\]

Answer 7

so what do we say for part a?

Answer 8

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

Answer 9

ok and part b?

Answer 10

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

Answer 11

i dont know that one :(

Answer 12

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

Answer 13

oh okay.. :)

Answer 14

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

Answer 15

what do we say for part b?

Answer 16

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

Answer 17

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

Answer 18

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:
\(c=0.05 \cdot p \)

Answer 19

ok thanks :) i have more questions :)
