A company is upgrading office technology by purchasing inket printers, LCD monitors, and additianat memory chips. The total mumber of pleces of hardaare puchased is 48 : The cost of each inkjet primer is 5115 , the cost of each LCD monitor is $140, and the cost of each inemory chip is $90. The total amount of money spent on new hardware came to $5195. They putchased tao times as mary memory chips as they did LCD montors. Delermine the number of each that was purchased. White a linear system of equatons. Let x be the number of inkjet printers, y be the number of LCD moniliors, and z be the numbar of memory chps. Checee the comed aniwe below. E. A. x x+48y+90z=5195 x+y+z=140 −2y+z=115 ​ 115x+90z=5195 x+y+z=46 −2y+z=0 ​ 115x+140y+90z=5195 x+y+2z=48 −2y+z=33 ​ D. c. 115x+140y+90z=5195 x+y+z=48 −2y+z=0 ​
