monday

1. anderson sometimes mows lawns on

the weekend to make extra money. two
weeks ago, he mowed a
neighbor’s lawn for 1/2 hour and earned
$10. last week, he mowed his uncle’s
lawn for 3/2 hours and earned $30. this
week, he mowed the lawn of a community
center for 2 hours and earned $30.
which job(s) paid better than others?
explain your reasoning

Explanation:

Step1: Calculate neighbor's lawn rate

$\text{Tasa} = \frac{\$10}{\frac{1}{2}\text{h}} = \$20/\text{h}$

Step2: Calculate uncle's lawn rate

$\text{Tasa} = \frac{\$30}{3.2\text{h}} \approx \$9.38/\text{h}$

Step3: Calculate community center rate

$\text{Tasa} = \frac{\$30}{2\text{h}} = \$15/\text{h}$

Step4: Compare all hourly rates

$\$20/\text{h} > \$15/\text{h} > \$9.38/\text{h}$

Answer:

El trabajo de cortar el césped del vecino pagó mejor que los demás, con una tasa de $\$20$ por hora, seguida del centro comunitario con $\$15$ por hora, y el trabajo del tío con aproximadamente $\$9.38$ por hora.
