Answer:
The variable that you control, often referred to as the x.
Answer:
(a) 12 hours
(b) $220
Step-by-step explanation:
(a) First we plug in $364 for C
C=76+24h
364=76+24h
Subtract 76 from both sides
24h=288
Divide both sides by 24
h=12
She spent 12 hours fixing the drain
(b) First we plug 6 hours in for h
C=76+24(6)
Multiply it out
C=76+144
Add
C=220
It costs $220 for fixing a drain that takes 6 hours
To find the cost of one CD, we divide 38.04 by 4
38.04 ÷ 4 = 9.51
The answer is reasonable because it's an accurate answer.
