Question

You have $73.50. You earn additional money by mowing lawns. Then you purchase a new pair of shoes for $99.99 and have $23.51 leftmuch money do you earn mowing lawns?

Answer 1

The question provides the following information;

Money at hand = 73.50

Money earned = x

Purchases made = 99.99

Money left over = 23.51

These sets of numbers can be put into an equation as shown below;

(73.5 + x) - 99.99 = 23.51

This equation means what you had at the beginning plus what earned from mowing lawns is a total of 73.5 + x. Subtract the cost of shoes purchased from this total and you'll now have a balance of 23.51

We can now solve for the money earned from mowing lawns as follows;

(73.5 + x) - 99.99 = 23.51

Add 99.99 to both sides of the equation (in order to isolate the 73.5 + x on the left side of the equation). You now have;

73.5 + x = 123.5

Next you subtract 73.5 from both sides of the equation (in order to isolate the x on the left hand side)

x = 50

This means the money earned from mowing lawns is $50
