Write a system of equations to describe the situation below, solve using elimination, and fill in the blanks.Angie wanted to stock up on drinks for an upcoming party. First, she spent $44 on 12 cases of juice and 10 cases of soda, which is all the store had in stock. A few days later, she returned to the store and purchased an additional 12 cases of juice and 13 cases of soda, spending a total of $50. What is the price of each drink?The price for a case of juice is $____, and the price for a case of soda is $_________.
Q. Write a system of equations to describe the situation below, solve using elimination, and fill in the blanks.Angie wanted to stock up on drinks for an upcoming party. First, she spent $44 on 12 cases of juice and 10 cases of soda, which is all the store had in stock. A few days later, she returned to the store and purchased an additional 12 cases of juice and 13 cases of soda, spending a total of $50. What is the price of each drink?The price for a case of juice is $____, and the price for a case of soda is $_________.
Forming Equations: Let's denote the price of a case of juice as J dollars and the price of a case of soda as S dollars. We can write two equations based on the information given:First purchase: 12J+10S=44Second purchase: 12J+13S=50We will use these two equations to form a system of equations that we can solve using the elimination method.
Elimination Method: To use the elimination method, we want to eliminate one of the variables by subtracting one equation from the other. Since the coefficient of J is the same in both equations, we can subtract the first equation from the second to eliminate J.Subtracting the first equation from the second gives us:(12J+13S)−(12J+10S)=50−44
Solving for S: Performing the subtraction, we get:12J+13S−12J−10S=50−44This simplifies to:3S=6
Substitute S: Now we can solve for S by dividing both sides of the equation by 3:33S=36S=2So, the price for a case of soda is $2.
Solving for J: Now that we know the price of a case of soda, we can substitute S=2 into one of the original equations to find the price of a case of juice. Let's use the first equation:12J+10S=44Substituting S=2, we get:12J+10(2)=44
Final Answer: Now we solve for J:12J+20=44Subtract 20 from both sides:12J=44−2012J=24
Final Answer: Now we solve for J:12J+20=44Subtract 20 from both sides:12J=44−2012J=24Finally, we divide both sides by 12 to find J:1212J=1224J=2So, the price for a case of juice is also $2.
