A pet store receives a shipment of pet foods at the beginning of each month. Over a three month period, the store received 1700 pounds of dog food, 1165 pouds of cat food, and 365 pounds of bird seed. Write and solve a system of equations to find the number of pounds of pet food in each of the three shipments.

Pet food:........... 1st shipment ........... 2nd shipment ........... 3rd shipment

Dog food:...................... 60%........... ........... ........... 50% ........... ........... ........... 50%

Cat food:...................... 25%........... ........... ........... 35% ........... ........... ........... 45%

bird food:...................... 15% ........... ........... ........... 15% ........... ........... ........... 5%

I already know how to solve the math problem, once I get the three equations, but I can figure them out. So, pretty much if any one could figure out what the three equations are.
