Question

johnny earns $15 per hour dog walking. he wants to earn at least $105 to buy a new bike. which inequality represents how long johnny...
options:
15h > 105
15h < 105
15h ≥ 105
15h ≤ 105

Explanation:

Step1: Define Variables

Let \( h \) be the number of hours Johnny works. His earnings are \( \$15 \) per hour, so total earnings are \( 15h \).

Step2: Interpret "At Least"

"At least \( \$105 \)" means earnings are greater than or equal to \( 105 \). So the inequality is \( 15h \geq 105 \).

Answer:

\( 15h \geq 105 \) (corresponding to the option with this inequality)
