  • Hi Cindy! I wanted to organize a fundraiser for our basket-ball team.
  • Everyone will love it! I'll organize it now.
  • That's a great idea. How about a car wash?
  • Yay, sounds great!
  • We washed 47 vehicles in total and we raised $295.
  • So today, we charged $5 for cars and $9 for vans.
  • Car Wash (5$/car and 9$/van
  • So how many cars and vans did we wash in total?
  • First method is elimination.
  • Let's find out how many cars and vans we washed
  • #1: 5c + 9v= 295#2: 5c + 5v= 235
  • #1: 5c + 9v= 295#2: c + v= 47
  • #1: 5c + 9v= 295#2: (c + v= 47)5
  • 5c - 5c + 9v - 5v = 295 - 235
  • y= mx + b
  • 4v = 60 4 4
  • v = 15
  • Let "c"= carsLet "v"= vans
  • Now we'll plug it in the equation
  • c + 15= 47
  • c + v= 47
  • c= 32
  • Therefore, we washed 15 vans and 32 cars in total today.
  • c= 47 - 15
  • First we have to solve for one of the variables in an equation
  • Then we'll solve the it using the substitution method just to verify our answer
  • 5(47 - v) + 9v= 295
  • 235 - 5v + 9v= 295
  • c + v= 47
  • 235 + 4v= 295
  • c= 47 - v
  • 4v = 60 4 4
  • 5c + 9v= 295
  • {
  • v = 15
  • 4v= 295 - 235
  • But this time we'll use the other equation to prove our answer is correct.
  • Now we'll plug it in the equation like we did before.
  • 5c + 9(15)= 295
  • 5c + 135= 295
  • Therefore, we washed 15 vans and 32 cars in total today.
  • 5c + 9v= 295
  • c= 32
  • 5c= 295 - 135
  • 5c= 1605 5
