Answer:
a) 5%
b) 24%
Step-by-step explanation:
a) You buy a game for $40, and the sales tax is $2. What percent of the game price are you paying in sales tax?
Percentage you are paying in sales tax
= Sales tax / Sale price of the game × 100
= $2/$40 × 100
= 5%
b) Your doctor told you to eat 25 grams of fiber each day. You had 6 grams of fiber for breakfast. What percent of the 25 grams of fiber have you eaten so far?
The percent of 25 grams of fiber you have eaten so far =
6 grams/25 grams × 100
= 24%
Number of females = f
Total number of people in audience = n
0.4n = f
f + (f+ 100) = n
2f + 100 = n
Find n:
f = 0.4n --> Replace f with 0.4n in the equation 2f +100 = n
2(0.4n) + 100 = n --> Multiply out the brackets
0.8n + 100 = n --> Subtract 0.8n from both sides
100 = 0.2n --> To get n, multiply both sides by 5
n = 500
There were 500 people in the audience.
5/6x = -1/6 ...multiply both sides by 6/5
x = -1/6 * 6/5
x = - 6/30 reduces to -1/5
