The correct answer is 48%

There are 10 even numbers from 1 to 21.

That makes the probability of an even number 10 out 21.

10 / 21 x 100 = 48%

A youth group sells cookles for $8 a boxIf they spent 1000 buying the cookies, which equation below shows the profit () made by
Sonbull [250]

Answer:

D)        P = 8b - 1000

Step-by-step explanation:

Think about it,

First off

    If they spent 1000 from just buying the cookies. When you buy something you lose money. So that's -1000.

Secondly,

     If they charged $8 per box that would cost an additional eight dollars each time a cutomer perchased a box. Another way to show addition is multiplication.

Ex if someone bought 7 box and 8 dollars each it could be shown as either:

1. 7 + 7 + 7 + 7 + 7 + 7 + 7 + 7

2. 8 + 8 + 8 + 8 + 8 + 8 + 8

3.  7 x 8  or 8 x7                                                                                                                      

So 8b - 1000 would make the most sense.
