Retail Sales of Sweatshirts: Sandy's Sweatshirt shop sells college sweatshirts. White sweatshirts sell for $18.95 each and red ones sell for 19.95 each. If receipts for the sale of 30 sweatshirts total $572.90, how many of each color did the shop sell? How many white sweatshirts and red sweatshirts did the sweatshirt shop sell?

let the number of reds be x
let the number of whites be 30x
solve
19.95x + 18.95(30x) = 572.90
times 100
1995x + 1895(30x) = 57290
take it from there
