Write a system of equations to describe the situation below, solve using elimination, and fill in the blanks.A coffee shop is having a sale on prepackaged coffee and tea. Yesterday they sold 16 packages of coffee and 13 packages of tea, for which customers paid a total of $235. The day before, 33 packages of coffee and 13 packages of tea was sold, which brought in a total of $388. How much does each package cost?Per package, coffee costs $_ and tea costs $_.
Q. Write a system of equations to describe the situation below, solve using elimination, and fill in the blanks.A coffee shop is having a sale on prepackaged coffee and tea. Yesterday they sold 16 packages of coffee and 13 packages of tea, for which customers paid a total of $235. The day before, 33 packages of coffee and 13 packages of tea was sold, which brought in a total of $388. How much does each package cost?Per package, coffee costs $_ and tea costs $_.
Equations Setup: Let's denote the cost of a package of coffee as c dollars and the cost of a package of tea as t dollars. We can write two equations based on the information given:1. For the first day: 16c+13t=2352. For the second day: 33c+13t=388These two equations form our system of equations.
Elimination Method: To use elimination, we want to eliminate one of the variables. We can do this by subtracting the first equation from the second equation:(33c+13t)−(16c+13t)=388−235This simplifies to:17c=153
Solving for Coffee Cost: Now we can solve for c by dividing both sides of the equation by 17:c=17153c=9So, a package of coffee costs \(9\).
Substitution for Tea Cost: With the value of \( c \) known, we can substitute it back into one of the original equations to solve for \( t \). Let's use the first equation:\(\newline\)\( 16(9) + 13t = 235 \)\(\newline\)\( 144 + 13t = 235 \)
Solving for Tea Cost: Now, we subtract \(144\) from both sides to solve for \( t \):\(\newline\)\( 13t = 235 - 144 \)\(\newline\)\( 13t = 91 \)
Solving for Tea Cost: Now, we subtract \(144\) from both sides to solve for \( t \):\(\newline\)\( 13t = 235 - 144 \)\(\newline\)\( 13t = 91 \)Finally, we divide both sides by \(13\) to find the value of \( t \):\(\newline\)\( t = \frac{91}{13} \)\(\newline\)\( t = 7 \)\(\newline\)So, a package of tea costs 7.
