Hervenson is working two summer jobs, making $12 per hour at Mcdonald's and making $8 per hour washing cars. In a given week, he can work at most 20 total hours and must earn a minimum of $200. If Hervenson works 15 hours at McDonalds, determine the minimum number of whole hours washing cars that he must work to meet his requirements. Write a system of inequalities to describe Hervenson's situation.

step-by-step explanation:

y = i/2 xtnop + (3i/2 tnop+ 1)

step-by-step explanation:

the picture is the step by step explanation.

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
