The girls tennis team was interested in raising funds for an upcoming trip. The team sold tumblers for $10 and sun hats for $5
gtnhenbr [62]

The equations that can be used are 10T + 5S = 190 and T + S = 30.

<h3><u>Equations</u></h3>

Given that the girls tennis team was interested in raising funds for an upcoming trip, and the team sold tumblers for $10 and sun hats for $5, and when the sales were over, the team had earned $190 and sold 30 total products, which included a mix of tumblers and hats, to determine which equations can be used to represent the situation, the following calculations must be made:

  • T + S =190
  • -It cannot be used because it has any relationship with the price of the products.

  • 10T + 5S = 30
  • -It cannot be used because it only considers the quantity variable.

  • T + S = 30
  • -It can be used as it shows the amount of products sold.

  • 10T + 5S = 190
  • -It can be used because it relates the total price to the quantity of each product.

  • T + S = 15
  • -It cannot be used because it only considers the price variable.
  • 5T + 10S = 190
  • -It cannot be used because it erroneously relates the price of each product.

Therefore, the equations that can be used are 10T + 5S = 190 and T + S = 30.

Why not?<br> If 4 + 6 = 10, does (4 + 6) X 3 = 10 X 3? Why<br> or why not?
IgorLugansk [536]

Answer:

It would be 10*3

Step-by-step explanation:

If we follow the rule of BIDMAS or BODMAS, they both have Brackets to be done first.

By meaning we must do 4+6 as it is in the bracket. Then we multiply our answer by 3.
