Question

Rita earns $10 per hour. She puts 5% of her earnings in savings. Write an inequality to find how many hours h Rita must work to save at least $25.

Answer 1

10 * h * 0.05 >= 25
h >= 50

Answer 2

Answer: tex]0.5h\geq25[/tex]

Step-by-step explanation:

Given : Rita earns $10 per hour.

Rita's Total earning = $10 x (number of hours she worked )

Let h denotes the number of hours she worked.

Then , Rita's Total earning = 10 h

Also,She puts 5% of her earnings in savings.

So , Savings=  5% of (Rita's Total earning)

Savings= 0.05 x (10h)  [we convert percent into decimals by dividing it by 100]

Savings=0.5h

Then, the inequality to find how many hours h Rita must work to save at least $25

Savings ≥ $25

$\Rightarrow\0.5h\geq25$

Hence, the required inequality : $0.5h\geq25$
