Real World Application System of Equations

A hotel offers two activity packages. Package A costs $192 and includes 3 hours of horseback riding and 2 hours of parasailing. Package B costs $213 and includes 2 hours of horseback riding and 3 hours of parasailing. Which system of equations below could be used to solve for the price of each hour of horseback riding and parasailing?

• 3h + 3p = 192

  2h + 2p = 213

• 2h - 2p = 192

  3h - 3p = 213

• 3h - 2p = 192

  2h - 3p = 213

• 3h + 2p = 192

  2h + 3p = 213

Suppose you got 8 mangoes and 3 apples for $18 and 3 mangoes and 5 apples for $14.50. Which system of equations below represents how you could find the cost of each mango and apple?

• 5m + 3a = 18

  3m + 8a = 14.50

• 5m + 8a = 18

  3m + 3a = 14.50

• 8m + 3a = 18

  3m + 5a = 14.50

• 8m + 5a = 18

  3m + 3a = 14.50

Kensington's talent show will feature 12 solo acts and 2 ensemble acts. The show will last 90 minutes. The 6 solo performers judged best will give a repeat performance at a second 60-minute show, which will also feature 2 ensemble acts. Each solo act lasts x minutes, and each ensemble act lasts y minutes. Which system of equations below could be solved to find the length of each act?

• 6x + 2y = 90

  12x + 2y = 60

• 6x - 2y = 90

  12x - 2y = 60

• 12x + 2y = 90

  6x + 2y = 60

• 12x - 2y = 90

  6x - 2y = 60

The school took in $52 on the second day by selling 3 senior citizen tickets and 2 child tickets. Which equations represents the system that could be used?

• 1s + 3c = 38
  2s + 3c = 52

• 3s + 1c = 38
  3s + 2c = 52

• s + c = 38
  s + c = 52

• 3s + 3c = 38
  1s + 2c = 52
