Jimmy is going to the store to buy candles. Small candles cost $3.50 and large candles cost $5.00. He needs to buy at least 20 candles, and he cannot spend more than $80. Let x represent the number of small candles and y represent number of large candles.
Do the following steps:
(a) Write a system of linear inequalities to represent the situation.

(b) Identify 2 solutions to the system of linear inequalities.

(c) Verify both solutions are valid by showing work to verify they satisfy both linear inequalities.
