You must make 4 deliveries per hour with Plan A to earn as much as Plan B.

Step-by-step explanation:

Plan A;

Earning per hour = $5

Per delivery earning = $0.75

Let,

x be the number of deliveries.

A(x) = 5 + 0.75x

Plan B;

Earning per hour = $7

Per delivery earning = $0.25

B(x) = 7 + 0.25x

For earning as much as B.

A(x) = B(x)

$5+0.75x=7+0.25x\\0.75x-0.25x=7-5\\0.5x=2$

Multiplying both sides by 0.5

$\frac{0.5x}{0.5}=\frac{2}{0.5}\\x=4$

You must make 4 deliveries per hour with Plan A to earn as much as Plan B.
