a) $36 for 4 hours

b) $27 for 3 hours

c) $45 for 5 hours

d) $18 for 2 hours

Answer 1

All of the answer choices given are equivalent ratios to Mike earning $9 per hour. To determine this, we divide the total amount earned by the number of hours worked in each option, and each one results in the original wage of $9 per hour.

Step-by-step explanation:

The student is asking about equivalent ratios, specifically to find which one of the provided choices is not equivalent to the ratio representing Mike's earnings of $9 per hour.

1. To check if each option is an equivalent ratio, we divide the total amount earned by the number of hours worked.
2. For option a) $36 for 4 hours: 36 ÷ 4 = $9 per hour.
3. For option b) $27 for 3 hours: 27 ÷ 3 = $9 per hour.
4. For option c) $45 for 5 hours: 45 ÷ 5 = $9 per hour.
5. For option d) $18 for 2 hours: 18 ÷ 2 = $9 per hour. All of the provided options are equivalent to the original ratio.

Therefore, none of the answer choices provided are incorrect; they all represent equivalent ratios to Mike earning $9 per hour.
