Problema Solution
Susan's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A $4.80 coffee costs Susan per pound, and type B coffee costs $5.95 per pound. This month, Susan made 127 pounds of the blend, for a total cost of $688.95. How many pounds of type A coffee did she use?
Answer provided by our tutors
let 'x' represent the pounds of $4.80 coffee used, then '127-x' represents the pounds of $5.97 coffee used
688.95 = x*4.80 + (127-x)5.95
solving for 'x' we have x=58
127 - 58 = 69
58 pounds of $4.80 coffee was combined with 69 pounds of $5.97 coffee
