7-9.

Adam earns $\36$ for every four hours of work. If he continues to be paid at the same rate:

1. How long will it take him to earn $\144$? Show and explain your reasoning.

$\144\div\36=4\text{ sets of } 4\text{ hour seach|}$

$16$ hours

2. How long will it take him to earn \$222? Show and explain your reasoning.

$222 ÷ 36 = \text{ how many sets of } 4 \text{ hours each?}$

3. How could you describe his rate for a $40$-hour work week? For a $7$-hour day? Show and explain your reasoning.

If Adam makes $36$ for every $4$ hours, how much does he make for every hour?
Now find what he makes for $40$ hours and $7$ hours.

$360$ for a $40$-hour week, $63$ for an $7$-hour day.
