Beth earns $54 per day and $10 for each extra hour she works. Ray earns $60 per day and $8 for each extra hour he puts in. They both work five days a week. The equations show their weekly earnings with respect to how many extra hours they work. Beth: y = 270 + 10x Ray: y = 300 + 8x

For Beth, we know that she works 5 days a week and that she earns $54 dollars per day. Next, add the $10 dollars for each extra hour of work. p stands for the amount she gets paid.

(54 * 5) + (10 * x) = p

For Ray, do exactly the same things you did for Beth but put in his earnings.

(60 * 5) + (8 * x) = p
