Answer:
Dana will have to spend $47.67.
Step-by-step explanation:
Dana needs 300 pickets for her colorful picket fence.
As she needs equal amount for 4 colors, so for each color she will need bulbs
She already has 32 red, 26 yellow, 9 green and no blues. She wants equal amounts of each of her 4 selected colors.
So, additional number of bulbs she needs are :
Red =
Yellow =
Green =
Blue =
Now, cost of 1 bulb = $0.25
You get 20% discount if you purchase 50 or more bulbs of the same color and 30% off if you purchase 60 or more of one color.
Cost for red bulbs = dollars
Cost of yellow bulbs = dollars
Cost of green bulbs = dollars
After 30% off, the price becomes: dollars
Cost of blue bulbs = dollars
After 30% off, the price becomes: dollars
Total cost of all bulbs = dollars
Hence, Dana will have to spend $47.67.
