1.       Given numbers:

=> $8 per hour by tutoring

=> $7.50 per hour by walking the dogs

=> You have 15 hours available

=> You need to make atleast $115 in walking the dogs.


let’s assign a variable to use.

Let a = tutoring

Let b = walking the dogs

=> a + b = 15

=> 8a + 7.5b = 115

=> 8a + 7.5(15 - a) = 115

=> 8a = 112.5 = 115

=> 8a = 115 – 112.5

=> 8a = 2.5

=> 8a / 8 = 2.5 / 8

=> a = 0.3125

=> b = 15 – 0.3125

=> b = 14.6875
