Step-by-step 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
