What are the three standard deviations to the right and the left of the mean. Show all work

emily solved for a part when she should have solved for the whole. 875,000 should be the numerator of the equivalent ratio. 70 x 12,500 is 875,000. so the answer is 100 x 12,500 which is 1,250,000.

the closest answer i got was 75 divided by 9 = 8.3
