Q. Write a system of equations to describe the situation below, solve using elimination, and fill in the blanks.Lowell City Cafe recently introduced a new flavor of coffee. They served 67 grande cups and 36 jumbo cups of the new coffee today, which equaled a total of 48,781 grams. The day before, 67 grande cups and 64 jumbo cups were served, which used a total of 65,721 grams. How much coffee is required to make each size?There are _ grams in a grande cup of coffee and _ grams in a jumbo one.
Define variables: Define variables for the grams of coffee per grande cup g and per jumbo cup j. We have two scenarios: 67 grande cups and 36 jumbo cups totaling 48,781 grams, and 67 grande cups and 64 jumbo cups totaling 65,721 grams. This leads to the equations:1. 67g+36j=48,7812. 67g+64j=65,721
Eliminate variable: Eliminate variable g by subtracting the first equation from the second:(67g+64j)−(67g+36j)=65,721−48,78128j=16,940
Solve for j: Solve for j:j=2816,940j=605
Substitute and solve: Substitute j=605 into the first equation to solve for g:67g+36(605)=48,78167g+21,780=48,78167g=48,781−21,78067g=27,001
Final solution: Solve for g:g=6727,001g=403
