you are shopping for disposable cameras to hand out at a party. the daytime cameras costs 2.75 dollars and the flash camera cost
grigory [225]

Solving a compound inequality for this solution gives solution as;

13 daytime cameras and 7 flash cameras or 7 daytime cameras and 13 flash cameras

<h3>How to solve inequality problems?</h3>

Let the number of daytime cameras be x

Let the number of flash cameras be y

Thus, we have;

x + y = 20    ------(1)

Now, daytime cameras costs 2.75 dollars and the flash camera costs 4.25 dollars and you want to spend between 65 and 75 dollars, inclusive. Thus, the inequality to represent this are;

2.75x + 4.25y ≥ 65 and 2.75x + 4.25y ≤ 75

Solving the 3 compound inequalities simultaneously, we can say that the approximate values of the numbers of cameras are;

13 daytime cameras and 7 flash cameras or 7 daytime cameras and 13 flash cameras
