Question

a landscaper bought same decorative cement blocks from a landscaping supplier. the supplier charged 5% sales tax and the total came to $315. without the tax, the landscaper could have bought 6 more blocks for the same total cost. how many blocks did the landscaper buy?

Answer 1

Amount of tax=315*(5/105)=15
Cost of 6 blocks=15/6=2.5 each block
Number of blocks purchased = (315-15)/2.5
=120
