Tyler does squats and pushups. He wants to increase the number of each type of exercise by 20% by the end of the month. He currently does 25 pushups. If Tyler meets his goal, he will do a total of 13 more squats and pushups than he does now. Write an equation to show how many squats, x, Tyler does now.

Given:

Tyler wants to increase the number of each type of exercise by 20% by the end of the month.

Current number of pushups = 25

Total more squats and pushups than he does now = 13

To find:

The equation to show how many squats, x, Tyler does now.

Solution:

Let x be the number of squats Tyler does now.

Each type of exercise increased by 20% by the end of the month.

Current number pushups = 25

Increased number of pushups is 20% of 25.

Increased number of squats is 20% of x.

If Tyler meets his goal, he will do a total of 13 more squats and pushups than he does now.

Multiply both sides by 5.

Subtract 25 from both sides.

Therefore, required equation is and the number of current squats is 40.
