Answer 1

Explanation:

`\sf 5 \: pounds \longrightarrow 4 \: dollars`

`\sf 1\: pounds \longrightarrow (4)/(5) \: dollars`

`\sf 50\: pounds \longrightarrow (4)/(5)×50 \: dollars`

`\sf \longmapsto 40 \: dollars`

Answer 2

40 dollars

Explanation:

We can use a ratio to solve the problem

5 pounds 50 pounds

---------------- = -----------------

4 dollars x dollars

Using cross products

5 * x = 4 * 50

5x = 200

Divide by 5

5x/5 = 200/5

x = 40

40 dollars
