docker41 [41]

As the ratio 0.050:1 for Adalynn and the ratio 0.067:1 for Dwight are not equivalent, it shows that this is not a proportional relationship.

What is a proportional relationship?

Proportional relationships can be described as relationships between two variables that have equivalent ratios.

The ratio of Adalynn that planted 20 peach trees over 400 feet can be expressed as follows:

20:400

Divide through by 400, we have:

0.050:1

The ratio of Dwight that planted 18 plum trees over 270 feet can be expressed as follows:

Divide through by 270, we have:

0.067:1

Since the ratio 0.050:1 for Adalynn and the ratio 0.067:1 for Dwight are not equivalent, this implies that this is not a proportional relationship.

Arturiano [62]

Answer:

$56.25

Step-by-step explanation:

for every hour Dexter worked with his dad he made $12.50 since he worked with him 4.5 hours we have to multiply 12.50*4.5 or if easier add 12.5 four and a half time 12.5+12.5+12.5+12.5= 50 + 6.25 ( which is half of $12.50 because he only worked half an hour) = $56.25
