Explanation:

Givens

• Frederick earns $10 per hour at the grocery store.
• He earns $8.50 per hour mowing lawns.
• He worked 35 hours last week.

`x` represents hours mowing lawns, which make him earn $8.5 each.

`y` represents the total earnings, mowing lawns plus grocery store.

Now, we know that he worked 35 hours in total. So, if he worked
`x` mowing lawns, then he worked
`35-x` hours in the grocery store, which represents +$10 per hour. So, this situation can be expressed as

`y=8.50x+10(35-x)`

Then, we solve the operations

`y=8.50x+10(35-x)\\y=8.50x+350-10x\\y=-1.5x+350`

Therefore, the right choice is B. y = -1.5x + 350
