Question

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?

Answer 1

`t = dn`

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.

`Total\ Earnings\ (t) = Charges\ (d) * Number\ (n)`

This gives:

`t = d * n`

`t = dn`
