John earns a total of t dollars mowing n lawns. He charges d dollars per lawn. Which equation shows the proportional relationship between the total John earns and the number of lawns he mows?

Step-by-step explanation:

Given:

Total Earnings = t dollars

Charges per lawn = d dollars

Number of lawn = n

Required:

Find the equation that describes the above illustration

To get the equation of proportionality of this system; we simply multiply the charges by the numbers of lawn;

i.e.

This gives:

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
