Answer :
y = 30 + 5x! this is because he makes $30 no matter what so we won’t be multiplying it so it will not have a variable (x) next to it. then he gets an “additional” $5 an hour for every hour he baby sits. since if it is not always a solid like the $30 because he could babysit for 2 hours or 20. it has the variable (x) next to it!
