Your daughter babysits and charges $8 per hour.Select the function that models the amount of money she earns when babysitting for h hours.B(h)=8h B(h)=8+h B(h)=8h B(h)=h+8 B(h)=8h Correct! Since she earns $8 for each hour she babysits, multiply 8 times the number of hours.Your business currently has 12 employees. You plan to add three new employees each year for the life of your business. Which function below models your plan? Note that N represents the number of employees while y=0 corresponds to the current year.N(y)=12y+3 N(y)=12-3y N(y)=36+y N(y)=12+3y N(y)=12+3y Correct! 3y is the correct interpretation of adding three employees each year while the 12 accounts for the 12 current employees. 1 / 4

2 The temperature outside is currently 50 degrees Fahrenheit and decreasing at a rate of 2 degrees per hour.Choose the function that models this scenario.T(h)=50h+2 T(h)=50h-2 T(h)=50+2h T(h)=50-2h T(h)=50-2h Correct! Since the temperature is decreasing each hour, subtract 2h from 50.The cost to mail a package that weighs z ounces is given by the function C(z)=$2.50+0.08z .How much would it cost to mail a package that weighs 14 ounces?
