Inga [223]
Ok so she wants but 5 crates of apples. And each crate cost 12.50 so you would multi 12.50 times 5, which is 62.05. She so wants to buy one crate of pears. One crate of pairs is 18.75. Since she is only buying one you don't need to multiply it but anything. But now you have to figure out the cost of the apples and pears together. So just add 62.05 and 18.75 together which is 80.80

George sold 18, 22, 26, 12, 25, 20, and 19 cars per month over the past seven months. He followed the steps below to
ikadub [295]

Answer:

George made the first mistake by multiplying by 7 instead of 8

Step-by-step explanation:

The total cars needed to have a mean of 24:

24 x 8 = 192

Total cars sold during the seven months:

18 + 22 + 26 + 12 + 25 + 20 + 19 = 142

Subtract the total cars sold from the total cars needed:

192 - 142 = 50

George needs to sell 50 cars in the eight month in order to have an average of 24 cars sold per month.
