Question

jack has saved $45. he got a summer job mowing lawns, and gets $6 for every lawn he mows. how many lawns does jack need to mow to save exactly $87, the cost of a concert ticket? solve for the value of m. solve on paper, or show your work below. then enter your answer on zearn. 6m + 45 = 87 m = \square

Explanation:

Step1: Subtract 45 from both sides

To isolate the term with \( m \), we subtract 45 from both sides of the equation \( 6m + 45 = 87 \). This gives us \( 6m + 45 - 45 = 87 - 45 \), which simplifies to \( 6m = 42 \).

Step2: Divide both sides by 6

Now, to solve for \( m \), we divide both sides of the equation \( 6m = 42 \) by 6. So, \( \frac{6m}{6} = \frac{42}{6} \), which simplifies to \( m = 7 \).

Answer:

\( m = 7 \)
