Answer :
Let's solve the problem step by step to find an inequality that represents the number of lawns Kevin needs to mow.
1. Identify the known values:
- Kevin has already saved [tex]$65.
- He earns $[/tex]15 for each lawn he mows.
- The bike costs [tex]$175.
2. Define the variable:
- Let \( x \) be the number of lawns Kevin needs to mow.
3. Set up an equation to determine Kevin's total savings:
- The money Kevin will have after mowing \( x \) lawns is the sum of his current savings and the money he earns from mowing lawns.
- Therefore, the expression for the total money Kevin will have is:
\[
65 + 15x
\]
Here, \( 65 \) is the amount he has already saved, and \( 15x \) is the money he earns from mowing \( x \) lawns.
4. Set up the inequality:
- Kevin needs at least $[/tex]175 to buy the bike. Therefore, the expression for his total savings should be greater than or equal to $175.
- This can be written as:
[tex]\[
65 + 15x \geq 175
\][/tex]
5. Choosing the correct inequality from the options:
From the options provided, the correct inequality is:
[tex]\[
175 \leq 65 + 15x
\][/tex]
This inequality shows the condition under which Kevin has saved enough money to buy the bike.
