Question

the costs of two sound systems were decreased by $10. the original costs of the systems were $90 and $60. without calculating, which had a greater percent decrease? explain

Answer 1

The $60 system had a greater percent decrease. Percent is essentially part/whole so when the part is the same, the percent is greater when the whole is smaller. Dividing my a smaller number = bigger number.
