Question

Brigida sold 4 less than 8 times as many boxes of cookies as Ava. If Brigida sold 84 bo how many did Ava sell?​

Answer 1

Explanation:

84 x 8 is 672 so if it said 4 times less it says it's 8 - 4 so it 4 and 84 x 4 is 336

Answer 2

Answer is 11 boxes for Ava

Step by step.

Brigida sold 84 boxes. This amount is 8x -4 boxes than Ava. Put this into an equation.

8x -4 = 84

Add 4 to each side to isolate x

8x -4 +4 = 84 + 4

8x = 88

Solve for x divide both sides by 8

8/8 x = 88/8

X = 11
