Question

Breon wants to buy a new sound system for $145.00. He already has saved $65.00 and makes $20 for each lawn that he mows. Write an equation to show how many lawns Breon must mow in order to have enough money for his new sound system.

Answer 1

4 lawns

Explanation:

You can set up an equation to find out how many lawns Breon must mow to have enough money for his new sound system.

• Let x represent the number of lawns he needs to mow.

Breon's savings: $65.00

Additional earnings from mowing x lawns: $20x

• The total amount he needs to reach his goal of $145.00 for the sound system is:

Total cost of sound system: $145.00

Now, you can write the equation:

Savings + Earnings from mowing lawns = Total cost of sound system

65 + 20x = 145

• This equation represents the situation.
• To find out how many lawns Breon must mow, you can solve for x:

20x = 145 - 65

20x = 80

Now, divide both sides by 20 to solve for x:

x = 80 / 20

x = 4

So, Breon must mow 4 lawns in order to have enough money for his new sound system.
