7) You want to cut a rectangular poster with an area of at least 60 square inches. The length is 7.5 inches. What is the minimum width of the poster (keep in mind the area of
a rectangle is L x W = A
Length x Width = Area). Write inequality and solve for Width
(W).
8) The total cost of 3 apples and 4 oranges is $5.45. The cost of the oranges is $0.75
each. Write the equation and solve for A (cost of one apple).
