Question

Cooper just measured himself and found out that he is 62 inches tall, which is 24% taller than the last time he measured. How tall was he last time?

Answer 1

47.12in

Explanation:

Let the last measurement be x

Current measurement= 62 in

Percent increase = current- previous/current *100

24= 62- x/62 *100

24= (6200-100x)/62

cross multiply

24*62= 6200-100x

1488= 6200-100x

100x= 6200-1488

100x= 4712

Divide both sides by 100

x= 4712/100

x= 47.12in
