When Sandra ordered candy for her store, she received three types of boxes containing the chocolate bars. The boxes are labeled x , y and z. If box x contains 10 bars, and box y contains 20 bars and box z contains 15 bars then the total number of bars is represented in the following equation:
T = 10x + 20y + 15z
If Sandra received 70 type x boxes, 30 type y boxes and 20 type z boxes, find the total number of bars she received?
Answer: 1600
Steps:
We must find out the total number of bars received in each box type as follows:
box x = 10 (70) = 700
Box y = 20 (30) = 600
box z = 15 (20) = 300
The total number of bars received will be the addition of all the above as follows:
T = 700 + 600 + 300 = 1600 chocolate bars.
