A customer at a store paid $40 for 2 new pillows and 3 new rugs. At the same store, a second customer paid $15 more than the first customer for 3 new pillows and 5 new rugs. The price of each pillow is the same, and the price of each rug is the same. Which system of equations can be used to find the price in dollars of each pillow, p, and each rug, r?
2p + 3r = 40 and 3p + 5r = 15
3p + 2r = 40 and 5p + 3r = 55
2p + 3r = 40 and 3p + 5r = 55
2p + 3r = 55 and 3p + 5r = 40
A customer paid a total of $33.00 for 65 photographs of her dog. Some of the pictures were glossy, and the rest were matte. Each glossy picture cost $0.18. Each matte picture cost $0.12. Which system of equations can be used to find g, the number of glossy pictures, and m, the number of matte pictures the customer bought of her dog?
g + m = 65 and 0.18m + 0.12g = 33.00
g + m = 65 and 0.18g + 0.12m = 33.00
g + m = 33.00 and 0.18g + 0.12m = 65
g + m = 65 and 0.18g + 0.12m = 65
