When the women's soccer team won the state championship, the parent boosters welcomed the team back to school with a balloon bouquet for each of the 18 players. the parents spent a total of $94.32 (excluding tax) on foil balloons that cost $1.94 each and latex school-color balloons that cost $0.17 each. each player received 10 balloons, and all the balloon bouquets were identical. how many of each type of balloon did each bouquet include?
each bouquet included
nothing foil balloons and
nothing latex balloons.

  Each bouquet included 2 foil balloons and 8 latex balloons.

Step-by-step explanation:

Let f represent the number of foil balloons in each bouquet. Then 10-f is the number of latex balloons. The problem statement tells us the cost of all of the bouquets is ...

  18(1.94f +0.17(10-f)) = 94.32

We can divide by 18 to get ...

  1.94f +1.70 -0.17f = 5.24

  1.77f = 3.54 . . . . . . . . . . . . subtract 1.70

  f = 3.54/1.77 = 2 . . . . . . . . divide by the coefficient of f

The number of latex balloons is 10-2 = 8.

Each bouquet included 2 foil and 8 latex balloons.

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )
