He earns more per hour parking cars than working at Haul-Mart, so his earnings are greatest when he works the maximum number of hours parking cars.

Since he wants to spend at most 10 hours parking cars, he should park cars for 10 hours and work at Haul-Mart for the other 6 hours.

His earnings are then 10($8)+6($7) = $80+$42 = $122.
