Staples has a discount on flash drives and boxes of computer paper. It offers flash drives for $6 each and boxes of computer pap
er for $40 each box. If total sales on these discount items is $4200 for the week, and customers bought 5 times as many flash drives as boxes of computer paper, how many boxes of computer paper were sold?
1 answer:
60 boxes of computer paper would have been sold.
Explanation:
To solve this equation you need an equation. You could also use the 5D process but the (6D) or an equation is more efficient as well as being less time consuming. The equation would be:
4200= (x•40) + (x•5)•6)
However, because the equation has so many parentheses, I am going to use the 5D process to try to find X. Basically you choose a random number and try to substitute it in for X, and you see if the number is too high or low. After awhile of guessing, I found that X = 60.
For a more detailed explanation of what the equation means and how it makes sense and is correct, you may view the following image above.
