Write a system of equations to describe the situation below, solve using elimination, and fill in the blanks.Nora wanted to stock up on drinks for an upcoming party. First, she spent $60 on 15 cases of juice and 15 cases of soda, which is all the store had in stock. A few days later, she returned to the store and purchased an additional 5 cases of juice and 9 cases of soda, spending a total of $28. 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.Nora wanted to stock up on drinks for an upcoming party. First, she spent $60 on 15 cases of juice and 15 cases of soda, which is all the store had in stock. A few days later, she returned to the store and purchased an additional 5 cases of juice and 9 cases of soda, spending a total of $28. What is the price of each drink?The price for a case of juice is $____, and the price for a case of soda is $____
Equation 1: Let's denote the price of each case of juice as j and the price of each case of soda as s. Nora spent $60 on 15 cases of juice and 15 cases of soda. This gives us the equation 15j+15s=60.
Equation 2: On her second trip, Nora purchased 5 cases of juice and 9 cases of soda for a total of $28. This gives us the equation 5j+9s=28.
Eliminate Variable: We now have a system of two equations. We need to eliminate one of the variables, j or s. To do this, we can multiply the second equation by 3 to match the coefficient of j in the first equation. This gives us 15j+27s=84.
Substitute and Solve: We now subtract the first equation from the new third equation to eliminate j. This gives us 12s=24, or s=2.
Final Solution: We substitute s=2 into the first equation and solve for j. This gives us 15j+15(2)=60, which simplifies to 15j+30=60. Subtracting 30 from both sides gives us 15j=30, or j=2.
