Someone Help! PLEASE! Jesse is taking the tests needed to join the math team. His scores were 89, 92, 94. What's the lowest score he can get on the fourth test and still have a 90 average?

The lowest score could be 85

Step-by-step explanation:

Let the  lowest score = x

(x + 89 + 92 + 94)/4 = 90                     Add the 3 scores you know

(x + 275)/4 = 90                                    Multiply both sides by 4

(x + 275) = 360                                     Remove the brackets.

x + 275 = 360                                       Subtract 275

x = 360 - 275

x = 85

the answer will be the last one
