A fruit stand sells two varieties of strawberries: standard and deluxe. A box of standard strawberries sells for $6, and a box of deluxe strawberries sells for $10. In one day the stand sold 110 boxes of strawberries for a total of $820. How many boxes of each type were sold?
standard strawberries ___ boxes
deluxe strawberries _____ boxes
Similar to the last problem.....we have this equation
(N)(6) + ( 110 - N)(10) = 820
6N + 1100 - 10N = 820
-4N + 1100 = 820 subtract 1100 from both sides
-4N = -280 divide both sides by -4
N = 70 = number of boxes of standards
110 - N = 110 - 70 = 40 = number of boxes of deluxes
