$5h + $10= $4.50h + 12

$.50h = $2

h = 4

Answer:

After 40 hours.

Explanation:

Let, after x hours both will charge the same total fees,

The amount charged by Beau = Base fees + the money for x hours

= 10 + 5 x

Similarly the amount charged by Jaime = Base fees + The money for x hours

= 12 + 4.50 x

⇒ 10 + 5x = 12 + 4.50x

⇒ 5x - 4.5x = 12 - 10

⇒ 0.5x = 2

x = 40

Hence, after 40 hours they will charge the same fee.
