Write a system of equations to describe the situation below, solve using any method, and fill in the blanks. The volleyball team
almond37 [142]

Answer: After washing 20 cars together, each team will have raised the same amount in total.

Step-by-step explanation:

Let x represent the number of cars that each each teams will wash for them to raise the same amount in total.

The volleyball team gets $4 per car. In addition, they have already brought in $24 from past fundraisers. This means that the total amount raised by the volleyball team after washing x cars would be

4x + 24

The wrestling team has raised $84 in the past, and they are making $1 per car today. This means that the total amount raised by the wrestling team after washing x cars would be

x + 84

For both amounts to be equal, the number of cars would be

4x + 24 = x + 84

4x - x = 84 - 24

3x = 60

x = 60/3

x = 20

saw5 [17]

Answer:

  • 102 sodas
  • 63 hot dogs

Step-by-step explanation:

Let s and h represent the numbers of sodas and hotdogs sold, respectively. The problem statement tells you ...

... s + h = 165

... s - h = 39

Add these two equations to get ...

... 2s = 204

... s = 102 . . . . . divide by w

... h = 165 - 102 = 63 . . . . use the first equation to find h from s

The vendor sold 102 sodas and 63 hot dogs at the basketball game.
