Answer:
The system of equation is given by:
a - m = 5
10*a + 15*m = 250
And the solution gives us a = 13 and m = 8.
Step-by-step explanation:
Desmond wants to pay 5$ more per hour Andrea than he pays Max. From that statement we can create one equation, that represents the difference between Max and Desmond payments, wich goes by:
a = m + 5
Desmond needs to fit the payment of his employees within a budget of $ 250, and he wants Andrea to work 10 hours while Max works for 15 hours. So the sum amount of time each employee works multiplied by the price of each hour should be equal to his budget. We have:
10*a + 15*m = 250
We have two equations and two variables, we can create a system that goes by:
a - m = 5
10*a + 15m = 250
In order to solve the system we can swap the value of a = m+ 5 into the second equation and solve for m, we have:
10(m+5) + 15m = 250
10m + 50 + 15m = 250
25m = 200
m = 8
In order to find the value of a, we put this value on the first equation:
a = m+5 = 8+5 = 13
