A data systems specialist makes $27 an hour for the first 40 hours she works
during a week and $35 an hour for each hour over 40 hours. Which piecewise
equation models her total weekly pay y in dollars as it relates to the number
of hours x that she has worked during the week?

D

Step-by-step explanation:

If 0<= x <= 40, then y = 27x

If x > 40,

First we have to calculate for first hours.So, it is 27*40 = 1080

Remaining hours = (x - 40)

Amount made in (x - 40)hours = 35*(x-40)

So, y = 35(x-40) + 1080

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.  

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x
