Answer: $11.20
Work: She buys each Jean for $32, and the markup is 35%. After a little multiplication, the new price is $43.20. When someone buys the Jeans at that price, she makes $11.20 because $43.20 is $11.20 more then the price she bought it for.
1 yr = 12 months...so 4 yrs = (12 x 4) = 48 months + 8 months = 56 months
4/5 = 56/x
cross multiply
4x = 280
x = 280/4
x = 70 months = 5 yrs and 10 months
There is no "last term." Since the pattern is increasing by .03 each time, then the pattern continues forever.
We want to compare averages. From the histogram we have we don't know the exact mean, but if we just assume the average in each bin is the midpoint of the bin we can make an estimate.
Supplier A has
mean = ( 22(64) + 27(66) + 26(68) + 15(70) + 10(72) )/(22+27+26+15+10)
mean = 6728/100 = 67.28 grams
Supplier B has mean 66.5
Answer: Choose Supplier A
