ALGEBRA ONE PLEASE HELP HIGH REWARD CLICK HERE HELP PLEASE IM OFFERING 100 POINTS
Sedbober [7]

The equation shows that the number of toys that must be bought for them to have equal profit will be 212 toys.

<h3>How to calculate the value?</h3>

From the information, it should be noted that the equation that can be used to represent the information about Jaclyn company will be:

= 2125 + (49.99 × x)

= 2125 + 49.99x

The equation that can be used to represent the information about Richie company will be:

= (39.95 × x)

= 39.95x

Therefore, we will equate both equations:

2125 + 49.99x = 39.95x

49.99x - 39.95x =2125

10.04x = 2125

x = 212

Therefore, the number of toys that must be bought for them to have equal profit will be 212 toys.
