Answer:

3 foil, 6 latex

Step-by-step explanation:

First, you can put all of these words words into equations. We know there are 162 ballons (18 players)(9 bouquets). So we can put it in the equation

x + y = 162

Since each foil balloon costs $1.92 and each Latex balloon costs $.19 and they all cost $124.20. We can put it in an equation:

.19x + 1.92y = 124.20

You then get the systems of equations:

x + y = 162

.19x + 1.92y = 124.20

solving for the equation, you get x = 54 and y = 108. BUT, you have to be careful. The problem said "How many of each type of balloon did each <em>bouquet</em>​ include?" So we need to divide both by 18 for the player because each player recieved on bouquet.

Rus_ich [418]
Rita's pay plus the overtime hrs, plus Tina's pay equals the total weekly wages(w)
[(11r) + 32] + 11t = w
That's one of the ways
Also, Rita's pay plus Tina's pay = weekly wages plus Rita's overtime hours pay
11r + 11t = w +32

Technically you just have to put the variables in the right places for it to make sense for the word problem
You can do the last example Good Luck!

Hope this helps :)
