A purchase is made under the following conditions. There is a 25% discount because of a sale, a 10% discount because of the size of the order, and a 5% discount for not using a credit card. The discounts are taken successively. If a customer pays $1,385.10, which includes an 8% sales tax, what was the original purchase price before tax and any of the discounts? (Successively means taken one at a time, not together.) Please just enter a number for your answer. No dollar signs, commas, or decimal point.
25 % discount means you pay 75 % of original
x (.75) now take a 10 % discount ...you pay 90%
x (.75)(.90) now take 5% off ...you pay 95%
x(.75)(.90)(.95) now ADD 8% tax
x (.75)(.90)(.95)(1.08) = $1385.10
x = $ 2000 original price
