Let the amount (in ounces) of solution A be a and that of solution B be b. You can write the following equations:

.55a + .80b = 90(.65) or .55a + .80b = 58.5

a + b = 90

By method of elimination or substitution, you can solve for a and b

a + b = 90 or a = 90 - b

.55(90 -b) + .80b = 58.5

49.5 -.55b + .80b = 58.5

.25b = 9

b = 36

a = 90 - 36 = 54

**Answer:**54 ounces of Solution A and 36 ounces of Solution B are required to make 90 ounces of a 65% salt solution

**Check work:**.55(54) + .80(36) = 58.5
