Regina: 6.50h + 16 Phil: 3(2.5h + 5)

Joseph: 7.50h + 10

How many hours will Regina and Joseph have to work in order to make the same amount of money in one week?

inorder For Regina and joseph to each earn the same amount of money regina will have to work 6.50x10.7+16  and joseph 7.50x10.+10

Step-by-step explanation:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

simple 80 pieces in 1 sercing so 80*47=3760+20=3780
