Question

on saturdays jackson cuts grass and washes cars. he charges $15 dollars per lawn and an additional fee for each car he washes. last sunday, jackson mowed 5 lawns and washed 10 cars. he made a total of $90 dollars. how much does jackson charge per car wash?

Answer 1

Let's denote the additional fee Jackson charges for each car wash as \( C \) dollars.

From the given information, we can set up two equations based on the services he provided:

1. The total income from mowing lawns: \( 5 \times 15 = 75 \) dollars.
2. The total income from washing cars: \( 10 \times C \) dollars.

The total income he made is $90. So, we can write the equation:

\[ 75 + 10C = 90 \]

Now, solve for \( C \):

\[ 10C = 90 - 75 \]
\[ 10C = 15 \]
\[ C = 1.5 \]

Jackson charges $1.5 for each car wash.
