Question

Raul works 2 h daily after school, Monday through Friday. On Saturdays he works 8 h at $2 more per hour than on weekdays. If he makes $142 per week, how much does he make per hour on weekdays?

Answer 1

Raul earns `$7` per hour on weekdays.

Explanation:

Let Raul works at per hour rate on weekdays be `$ x`, then,

Raul works at per hour rate on Saturdays be `$ (x+2)`

He makes total of `$142` per week (5 weekdays and Saturday)

`:.5 x*2+(x+2)*8=142 or 10 x+8 x =142-16` or

`18 x= 126 or x =126/18= $7` ,

Therefore, Raul earns `$7` per hour on weekdays. [Ans]
