Question

Ravi's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee costs Ravi $5.50 per pound, and type B coffee costs $4.05 per pound. This month's blend used four times as many pounds of type B coffee as type A, for a total cost of $520.80 . How many pounds of type A coffee were used

Answer 1

p represents the pounds of A

4p represents the pounds of B

 

5.50p + 4.05(4p) = 520.80

 

Can you solve for p?
