x·1/2·7/8·6/7·1/2 = 12 --> x = 64 Stickers
Answer:
$1.15
Step-by-step explanation:
P(red) = 1/5 [that says "probability of getting red is one fifth"
P(green) = 1/5
P(blue) = 1/5
P(yellow) = 1/5
P(purple) = 1/5
The reason the fractions are all the same is that there are equal numbers of each color. For example, if there were 7 marbles of each color, there would be a total of 35 marbles.
P(red) = 7/35 = 1/5
Similar for the other colors.

Answer:
a) $14.37 sales tax
b) $25.13 left on gift card
Step-by-step explanation:
Purchases: 78.50 + 32.00 = 110.50
Sales tax: 13%:
1% of 110.50 = 1.1050

rounded to 2 decimal places: $14.37
Total cost: 110.50 + 14.37 = $124.87
Gift card: 150.00 - 124.87 = 25.13
