+180 Terrell usually lifts two 20-pound weights 12 times. If he uses two 15-pound weights instead, how many times must Terrell lift them in order to lift the same total weight?
We will need to find out how many pounds he lifts.
Since he has 2 20 pounds this means that each time he lifts, he lifts 40 pounds.
He lifts 12 times so 40x12=480 pounds.
We divide by thirty because he uses 2 15 pounds.
This means that 480/30 = 16
He lifts 16 times
Hope this helped!
