Your budget requires you to earn at least $213 per week. You work two parttime
jobs. One is at a grocery store, which pays $10 per hour, and the other is mowing lawns, which pays
$14 per hour. Let x represent the number of hours you work at the grocery store and let
y represent the number of hours you work at mowing lawns. Write a linear inequality that
represents the different numbers of hours you can work at each job in order to meet your budget
requirements.


19.

Each table produced by a furniture company requires 1 hour in the assembly
center while each chair requires 2 hours in the assembly center. A total of 12 hours per day is
available in the assembly center. Write a linear inequality that shows the different numbers of hours
that can be spent assembling tables and chairs. Let x represent the number of hours spent
assembling tables and y the number of hours spent assembling chairs. Sketch the graph of the
inequality.


20.

A convenience store has a policy that its cash register will contain less than
$100 in paper money after dark. If the register only contains onedollar bills and fivedollar bills,
write a linear inequality that shows the different numbers of paper bills that can be in the cash
register. Let x be the number of onedollar bills and y the number of fivedollar
bills. Find one solution to the inequality.
