Step-by-step explanation:

The complete question is

Drew has 4 times as many baseball cards as Mark. Katie has 3 fewer than than half as many cards  as Mark. In all they have 162 baseball cards. How many does each have?

Number of Cards with Katies = 0.5 X -3

Sum of all the cards is equal to 162

X+4X + 0.5 X -3 = 162

5.5 X = 165

X = 30

Cards with Drew = 4 * 30 = 120

Cards with Katei = 15-3 = 12

What percentage of 23 is 924
monitta
Well, the answer to the question in your picture is $1200.

If x is the original price, and we took 23%, or 0.23 from that, we are left with 77%, or 0.77 of the full price.

So 0.77x = 924
x = 924/0.77
x = 1,200

1200 - 0.23(1200) = 924

924 = 0.77x
