Question

Dana needs 300 pickets for her colorful picket fence. She wants equal amounts of each of her 4
selected colors. She already has 32 red, 26 green, 9 yellow and no blue. How many more of each
color does Dana need to buy? If the bulbs cost 25 cents and you get 20% off if you purchase 50 or
more of the same color and 30% off if you purchase 60 or more of one color, how much does Dana
need to spend?

Answer 1

The correct answer to this question is $53.30. Being that she needs equal amounts, she needs 75 of each color.
She already has 32 red, so that leaves 43 more that she needs : costs 4325=$10.75
She already has 26 green, so that leaves 49 more that she needs. : costs 4925=$12.25

She already has 9 yellows, so she needs 66 more of those. 6625=$16.50. She only pays 70% of this because 30% gets knocked off. 70% of $16.50 = $11.55
She has no blues yet, so she needs all 75 of those. It would originally cost 7525=$18.75. She only pays 70% of this. 70% of $18.75 = $13.13
Adding together all of the amounts, leads to 10.75 + 12.25 + 11.55 + 18.75, which equals $53.30

Answer 2
