MEDAL REWARD!!! :)
Amanda's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee costs Amanda $4.30 per pound, and type B coffee costs $5.55 per pound. This month's blend used three times as many pounds of type B coffee as type A, for a total cost of $565.65. How many pounds of type A coffee were used?

Let A : the amount in lbs of type A coffee
B: the amount in lbs of type B coffee

You can set 2 equations:
Equation 1: B = 3A since there is 3 times the amount of B as in A
good so far?
