Problema Solution
You want to make a tower out of building blocks; you only have enough blocks to make your tower 10 inches high. You have already built the tower 7 inches high, and you only have 5 building blocks left: all exactly the same size. How tall is each of the 5 remaining building blocks? Write an equation to model the situation. Then solve the problem.
Answer provided by our tutors
presumably the blocks are being stacked on top of each other one-by-one
10-7=3, we have 3 inches remaining and we assume that the five blocks fill up that 3 inches
we have 5 blocks, with 10-7 inches left, so the inches per block would be:
(10-7)/5 = 3/5 = 0.6
each block is 0.6 inches tall
