Question

Ryan mows lawns in the summer. He charges $15 for every 1/2 hour of mowing. This is represented by the equation y=15x, where y is the total amount Ryan charges and x is the number of 1/2 -hour sessions of mowing. If Mr. Smith’s lawn takes 2 hours to mow and Mrs. Jones's lawn takes 3.5 hours to mow, how much more would Ryan charge Mrs. Jones than Mr. Smith?

$

Answer 1

Well there is 60 minutes in an hour, meaning there is 2 half hours (30 minutes) if it takes 2 hours to mow Mr. Smiths lawn he would have made $100.

y=15(4)

Mrs. Jones, will be charged $105.

y=15(7)

Mrs. Jones will be charged $5 more! hope this helped
