Answer 1

Answer:

Step-by-step explanation:

Given

there are 2.5 oranges per Pound

and 1.2 Grapefruit per Pound

In $ 50 one can buy 40 Pound Oranges

i.e. Oranges is $\frac{50}{40}=1.25\ \ per\ Pound$

In 50 $ one can buy 55 Pound Grapefruit

i.e. Grapefruit is $\frac{50}{55}=0.909\ \ \ per\ Pound$

If we have Enough money to buy 28 Pounds of Grapefruit

$28\times \frac{50}{55}=25.45$

In 24.45 $ we can bought $\frac{24.45}{1.25}=19.56 Pounds$

19.56 pounds meaning $19.56\times 2.5=48.9\ oranges\approx 49\ oranges$
