Final answer:
To find the number of squats Tyler does now, set up an equation based on the given information and solve for x. By solving the equation, we find that Tyler currently does 85 squats.
Step-by-step explanation:
To solve this problem, you need to set up an equation based on the given information and then solve for the number of squats Tyler does now, denoted as x.
According to the problem, Tyler wants to increase the number of each type of exercise by 20% by the end of the month. So the number of push-ups Tyler will do by the end of the month will be 25 + 25 * 0.2 = 30 push-ups. And the number of squats Tyler will do by the end of the month will be x + x * 0.2 = 1.2x squats.
It is also mentioned in the problem that Tyler will do a total of 13 more squats and push-ups than he does now. So we can set up the equation: 30 + 1.2x = x + 13. Solving this equation will give us the number of squats Tyler does now.
30 + 1.2x = x + 13
0.2x = 17
x = 85.
Therefore, Tyler currently does 85 squats.
