At a store 2 pillows and 3 pillows cases together cost $73.8 . The total cost of 3 pillows and 4 sheets is $120.82 . If the price if the pillow is 3 times as much as the price of the pillow case, what is the total costs of 5 pillows and 7 sheets ?

for me what is finding a good play list and going out because i can not lay down and relax so i usually go to a coffee shop. i also use the gum trick and this actually works. another advice is highlighting subjects it really does me remember certain things
