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
