Answer 1

Answer:

A 125

Step-by-step explanation:

(40x4) +25

Answer 2

Answer:

Step-by-step explanation: A

First you substitute and compute for x

C=40x+25 goes to C = 40(4) +25.

Then you multiply 40 tines 4 and get 160 and add 25 and get $165.

Step-by-step explanation: B

First you take tge equation c =40 x +25 and change it to 265= 40x +25.

Then you use inverse operations and do

265 = 40x+25 then using inverse operation you first subtract 25 from 265. Which is 240

Then you take that 240 and divude it by 40 and get 6.

So, x=6 hours.
