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?

1 answer

Cost = Po + 0.05Po = $315
1.05Po = 315
Po = $300 = Initial price.

(315-300)/6blks = $2.50/blk

300/(2.50/blk) = 120 Blocks bought.
