Q. Write a system of equations to describe the situation below, solve using elimination, and fill in the blanks.Two friends visited a taffy shop. Rachel bought 2 kilograms of strawberry taffy and 5 kilograms of banana taffy for $43. Next, Devon bought 1 kilogram of strawberry taffy and 1 kilogram of banana taffy for $11. How much does the candy cost?A kilogram of strawberry taffy costs $_____, and a kilogram of banana taffy costs $_____.
Equations Setup: Let's denote the cost of a kilogram of strawberry taffy as S dollars and the cost of a kilogram of banana taffy as B dollars. We can write two equations based on the information given:1. For Rachel's purchase: 2S+5B=432. For Devon's purchase: S+B=11
Elimination Method: To solve the system using elimination, we want to eliminate one of the variables. We can multiply the second equation by 2 to align the coefficients of S:2(S+B)=2(11)2S+2B=22
New System of Equations: Now we have a new system of equations:1. 2S+5B=432. 2S+2B=22We can subtract the second equation from the first to eliminate S:(2S+5B)−(2S+2B)=43−22
Subtraction to Eliminate S: Performing the subtraction gives us:2S+5B−2S−2B=43−225B−2B=213B=21
Solving for B: Dividing both sides of the equation by 3 to solve for B:33B=321B=7So, a kilogram of banana taffy costs $7.
Substitute B to Find S: Now that we know the cost of banana taffy, we can substitute B=7 into one of the original equations to find S. We'll use the second equation:S+B=11S+7=11
Substitute B to Find S: Now that we know the cost of banana taffy, we can substitute B=7 into one of the original equations to find S. We'll use the second equation:S+B=11S+7=11Subtracting 7 from both sides to solve for S:S+7−7=11−7S=4So, a kilogram of strawberry taffy costs $4.
