A fitness challenge runs for 28 days and requires participants to complete an average of 80 push-ups per day. During the first half of the program, participants averaged 60 push-ups per day. How many push-ups per day must they average during the second half of the program to meet the challenge goal?

Explanation	Calculations	Help
$We name x as the average push-ups per day in the second half of the program.$	$x = average push-ups per day in the second half$
$We calculate the total push-ups needed for all 28 days.$	$Total push-ups needed = 80 \times 28 = 2240$
$We calculate the number of push-ups completed in the first 14 days.$	$Push-ups in first half = 60 \times 14 = 840$
$We find how many push-ups remain for the second half by subtracting.$	$Remaining push-ups = 2240 - 840 = 1400$
$We express the total push-ups in the second half as x times 14 days.$	$x \times 14 = 1400$
$We solve for by dividing both sides by 14 and simplifying the fraction.$	$x = \frac{1400}{14} = \frac{14 \times 100}{14} = 100$	Theory & Tactics Method Card EQUA1-A Click to view full details Theory & Tactics Method Card FDPR2-A Click to view full details
