Fred johnson total insurance premium is 1,200. his employer pays 60% of the total premium. how much does fred pay?

We can set up a proportion to find this

60      x
---  =
100   1200

then we cross multiply and divide to solve

60 times 1200 is 72000 divided by 100 is 720

now we know his employer pays 720 out of 1200

we subtract to find out how much he pays

1200-720 is 480

fred pays 480

ten, twenty , thirty

Step-by-step explanation:

So, the equation you have set up already, y = 2x + 10, models the cost of the membership and movies, with y as the total cost, and x as the number of movies. Here we can just plug in the x values to get the total costs. If x is zero, we get ten dollars total, if it is five, we get twenty dollars total, and if it is ten, we get thirty dollars total.
