Answer:
Step-by-step explanation:
$20 times 4=80
80 times 4=320
4 times 4= 16 weeks
15.5 weeks (or 15 and a half weeks).
Taylor starts at $10.
Each week she makes $20.
Since she already has $10, she only needs to save $310.
310 ÷ 20 = 15.5
Therefore, she will need to save $20 per week for 15 and a half weeks.
3x + 6 = 8 + 3x - 2
3x + 6 = 3x + 6
Bringing like terms on one side
3x - 3x = 6 - 6
0 = 0
18 = 2x + 4
2x = 14
x = 7
answer
first line: 1st box: 18 and 2nd box: 4
second line: $7 an hour
