Question

An electronics store makes a profit of $72 for every television sold and $90 for every computer sold. The manager’s target is to make at least $360 a day on sales from televisions and computers. Write a linear inequality and graph the solutions. What are three possible solutions to the problem?

Answer 1

72t + 90c >= 360

Three possible solutions can be found by subbing in any number for t and solving for c
(1) 72 (2) + 90c > = 360
144 + 90c >= 360
90c >= 360 - 144
90c >= 216
c >= 216/90
c >= 2.4
one solution is : t = 2 and c >= 2.4

(2) 72 (3) + 90c >= 360
216 + 90c >= 360
90c >= 360 - 216
90c >= 144
c >= 144/90
c >= 1.6
solution : t = 3 and c >= 1.6

(3) 72(1) + 90c >= 360
72 + 90c >= 360
90c >= 360 - 72
90c >= 288
c >= 288/90
c >= 3.2
solution : t = 1, and c >= 3.2

Answer 2

in my choices none of them have a decimal.
