Question

Every yard Johnnie mows he earns $7
how much money will Johnnie have in his account if he mowed at least 16 yards
show the inequality

Answer 1

To represent the amount of money Johnnie will earn based on the number of yards he mows, you can use the following inequality:

Let \( y \) be the number of yards Johnnie mows.

Since Johnnie earns $7 for every yard mowed, his earnings can be expressed as:

\[ 7y \]

Given that he mows at least 16 yards, we can set up the inequality:

\[ y \geq 16 \]

Now, substituting the minimum value into the earnings expression, we find the minimum amount Johnnie will have in his account:

\[
\text{Earnings} = 7y
\]
\[
7y \geq 7 \times 16
\]
\[
7y \geq 112
\]

So the inequality for Johnnie's earnings based on mowing at least 16 yards is:

\[ 7y \geq 112 \]

This means that Johnnie will have at least $112 in his account if he mows at least 16 yards.
