Sarah's mother is buying apples to make apple pies. the apples cost $3 per pound. sarah's mother has $40. how many pounds of apples can her mother buy?

40$ / 3$ = 13.33

or 3+3+3+3+3+3+3+3+3+3+3+3+3=39$
 add 1 pound for each 3$ you well get 13 pounds of apples

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
