150=60*x+20*x
150=80x
x=150/80
x=1, 875 hours

Complete question is;

The city of Minerva pays $916 per year for health insurance for each of its 72 municipal employees. What is the total cost that the city pays per year for health insurance?

Question 3 of 10
Bas_tet [7]

Answer:

A. y-5=1.5(x-4).

B. y=1.5x-1.

Step-by-step explanation:

The given line passes through (2,2) and (4,5).

The slope the given line can be found using the formula;

m=\frac{y_2-y_1}{x_2-x_1}

m=\frac{5-2}{4-2}

This gives m=\frac{3}{2}=1.5.

The slope-intercept form is y-y_1=m(x-x_1).

We substitute the second point to get:

y-5=1.5(x-4).

We expand to get:

y-5=1.5x-6.

y=1.5x-6+5.

y=1.5x-1.
