Step-by-step explanation: divide the increase by the original number and multiply the answer by 100: % increase = Increase ÷ Original Number × 100. If the answer is a negative number, that means the percentage change is a decrease.
We first work out how much Mary will earn in one hour by doing 97.50/6.5 = 15 We then multiply this answer by 8 to work out how much she is expected to earn in 8hours 15*8= 120 So Mary will earn $120 in 8 hours
