Answer:

Numbers of apples kept by Hannah was 9.

Explanation:

Let the numbers of apple bought be x.

Hannah bought three apples for $0.95

Cost of an apples =
(\$0.95)/(3)

Cost price of x apples =
(\$0.95)/(3)* x

She sold 3/4 of them at $.45 each.

Number of apples sold =
(3x)/(4)

Sell price or money earned by selling apples =
(3x)/(4)* \$0.45

Profit made by Hannah = $0.75

Profit = Sell price - Cost price


(3x)/(4)* \$0.45-(\$0.95)/(3)* x=\$0.75


(3x)/(4)* \$0.45-(\$0.95 x)/(3)=\$0.75


x* ((3)/(4)* \$0.45-(\$0.95 )/(3))=\$0.75


x=(\$0.75)/(((3)/(4)* \$0.45-(\$0.95 )/(3)))=36

Numbers of apples kept by Hannah:

=Total apples - Number of apples sold =
36-36* (3)/(4)=9

Numbers of apples kept by Hannah was 9.
