(20 Points)
48 burpees & 80 squats
48 burpees & 82 squats
46 burpees & 80 squats
46 burpees &. 82 squats

48 burpees & 80 squats

Step-by-step explanation:

Let burpees= x

Let squat = y

For every 12 burpees Melinda did, she did 20 squats.

X/y =12/20

20x= 12y

X= 0.6y

Melinda did a total of 128 squats and burpees

X+y= 128

But x= 0.6y

0.6y +y= 128

1.6y= 128

Y= 128/1.6

Y= 80

X+y= 128

X+80= 128

X=128-80

X= 48

100 *4% then divided 7 the number you got
