ALGEBRA – LESSON 89 Value Problems Be ready to grade the homework!

Anytime you are given enough information to write more than 1 equation, you are solving a system of equations. These problems can use substitution or elimination to solve. The focus on these problems is writing the correct equations before solving. You will write 2 separate equations.

Value Problems 85C + 75T = C = C + 75(C + 4) = C + 75C = 2380 C = 13 #1 Nancy spent $23.80 on treats to put in Gift of Love boxes for the needy children in her city. A candy bar costs 85c and a bag of trail mix costs 75c. Nancy bought 4 more bags of trail mix than candy bars. How many candy bars did she buy? T = C + 4

Value Problems 55C + 50T = C = C + 50(C – 3) = C + 50C – 150 = 1845 C = 19 #2 Myrna spent $18.45 on treats to put in Gift of Love boxes for the needy children in her city. A candy bar costs 55c and a bag of trail mix costs 50c. Myrna bought 3 more candy bars than bags of trail mix. How many candy bars did she buy? T = C - 3

Value Problems 400A + 250S = S = (140 – S) + 250S = – 400S + 250S = S = 10 #3 Tickets to a local movie were sold at $4.00 for adults and $2.50 for students. If 140 tickets were sold for a total of $545.00, how many student tickets were sold? A = S

Value Problems 300A + 150S = A = A + 150(258 – A) = A – 150A = A = 230 #4 Tickets to a local movie were sold at $3.00 for adults and $1.50 for students. If 258 tickets were sold for a total of $732.00, how many adult tickets were sold? S = 258 – A
