Sophia has saved $45. She got a summer job mowing lawns, and gets $6 for every lawn she mows. How many lawns does Sophia need to mow to save exactly $87, the cost of a concert ticket?

Respuesta :

Answer:

She needs to mow 7 lawns.

Step-by-step explanation:

The first step is to write the equation

45+6x = 87, where x is the number of lawns.

Subtract 45 from each side.

45+6x-45 = 87-45

6x = 42

Divide each side by 6

6x/6 = 42/6

x =7

She needs to mow 7 lawns.
