• 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
