Each plan utilizes a combination of 2 strength-training sessions and 3 aerobic exercise sessions per week.
Let y be the number of strength-training exercises per week.
Let x be the number of aerobic exercises per week.
For the beginner plan, the equation would be gotten as;
15y + 20x = 90 ------(eq 1)
The equation to represent the advanced plan would be;
20y + 30x = 130 -------(eq 2)
Multiply both sides of eq 1 by 4 to get:
60y + 80x = 360 ------(eq 3)
Multiply both sides of eq 2 by 3 to get:
60y + 90x = 390 ------(eq 4)
Subtract eq(3) from eq(4) we get:
10x = 30
Thus; x = 3
Then; 15y + 20(3) = 90
15y = 30
y = 2
Thus, the correct statement is:
"Each plan utilizes a combination of 2 strength-training sessions and 3 aerobic exercise sessions per week."
