Kim placed an order for 98 gizmos which cost $445. A package of 7 gizmos cost $30, and a package of 5 gizmos cost $25. How many packages of each type did Kim order?
Really not sure how to start it from there.. and how to put it into equations.

Hi fvaras89
Let :
x = package of 7 gizmos
y = package of 5 gizmos
1.
If Kim buys one x and one y, she will get 12 gizmos -----> 7*1 + 5*1 = 12
If Kim buys two x and one y, she will get 19 gizmos -----> 7*2 + 5*1 = 19
If Kim buys three x and two y, she will get 31 gizmos -----> 7*3 + 5*2 = 31
If Kim has to buy 98 gizmos, can you find the equation ? ----> 1st equation
2.
If Kim buys one x and one y, she will spend $55 -----> 30*1 + 25*1 = 55
If Kim buys two x and one y, she will spend $85 -----> 30*2 + 25*1 = 85
If Kim buys three x and four y, she will spend $190 -----> 30*3 + 25*4 = 190
If Kim has $445, can you find the equation ? -------> 2nd equation
