Change Image Delete

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. 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 60or more of one color.

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 43*25=$10.75
She already has 26 green, so that leaves 49 more that she needs. : costs 49*25=$12.25

She already has 9 yellows, so she needs 66 more of those. 66*25=$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 75*25=$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
