Ava works at a florist shop. she earns $7.50 an hour plus a fixed bonus for each bouqet she arranges. write an equation to determine how much money she will make in a week

Let X be the number of hours she worked per week, and Y be number of bouqet she arranged in whole week, and Z be the bonus for one bouqet

Then 7,5*x+Y*Z=payment for one week.
