Answer:
b. Kinsey must save $72 per month to achieve her goal.
Step-by-step explanation:
<em>Goal over 16 months:</em> $60 x 16 = $960
<em>Collected after 11 months:</em> $600
- $360 still needed
- 5 months lefts
$360 ÷ 5 = $72
2(4+39) = 39 + 4 = 43
43 x 2 = 86
Let the hours Kade worked = X
Theo would be X - 3 ( 3 less than Kade).
Now you have:
X + X -3 = 27
Combine like terms:
2x - 3 = 27
Add 3 to each side:
2x = 30
Divide both sides by 2:
x = 15
Kade worked 15 hours.
Theo worked 12 hours.
