a) To write the fraction as a percent, you simply multiply the fraction by 100%.
The fraction 83.33% is already a percent, so it doesn't need to be converted.
b) To write the decimal 0.063 as a percent, multiply it by 100%.
0.063 * 100% = 6.3%
c) To find the percent of students who have a cell phone, divide the number of students with a cell phone (792) by the total number of students (1220).
Percent = (792/1220) * 100% = 64.92%
d) To write the percent 96.55% as a decimal, divide it by 100%.
96.55% / 100% = 0.9655
a) To estimate each person's contribution to the total tip, multiply the total bill by the tip percentage and divide by the number of people.
Contribution per person = ($191.10 * 15%) / 10 = $2.85
b) To solve using a proportion, set up a proportion with the part and the whole.
x/100 = 34/83
Cross multiply and solve for x.
83x = 3400
x = 3400/83
x ≈ 40.96
a) To find what percent 77 is of 192, set up a proportion.
x/100 = 77/192
Cross multiply and solve for x.
192x = 7700
x = 7700/192
x ≈ 40.01%
c) To find the number of students in the entire class, set up a proportion.
26/x = 65/100
Cross multiply and solve for x.
65x = 2600
x = 2600/65
x = 40 students
b) To find how many goals Richard made, multiply the total number of goals (327) by the percentage he made (65%).
Goals made by Richard = 327 * 65% ≈ 212
To find the percent of the team's goals that Richard made, divide the goals he made (212) by the total team goals (327) and multiply by 100%.
Percent of team's made goals = (212/327) * 100% ≈ 64%
d) To find what percent of 21 is 7, set up a proportion.
7/x = 21/100
Cross multiply and solve for x.
21x = 700
x = 700/21
x ≈ 33.33%
a) To find the tax paid, multiply the list price ($128) by the tax rate (6.9%).
Tax paid = $128 * 6.9% ≈ $8.83
To find the total cost, add the list price and the tax paid.
Total cost = $128 + $8.83 ≈ $136.83
b) To find Jamie's sales for the week, subtract her base salary ($95) from her total earnings ($475).
Sales = $475 - $95 = $380
a) To find the percent of change, subtract the initial population from the final population, divide by the initial population, and multiply by 100%.
Percent of change = ((584 - 421) / 421) * 100% ≈ 38.7%
Since the final population is greater than the initial population, it is an increase.
b) To find the percent of markup, subtract the cost price from the selling price, divide by the cost price, and multiply by 100%.
Percent of markup = (($99.99 - $64.25) / $64.25) * 100% ≈ 36%
d) To find the lower sale price, subtract the discount from the regular price for both stores and compare the sale prices.
Store A's sale price = $59.99 * (1 - 10%) = $53.99
Store B's sale price = $64.99 * (1 - 15%) = $55.24
Since Store A's sale price ($53.99) is lower than Store B's sale price ($55.24), Store A sells the video game for the lower sale price.
c) To find the final balance with simple interest, multiply the principal ($660) by the interest rate (3.5%) and multiply by the time period (5 years). Then, add the result to the principal.
Final balance = $660 + ($660 * 3.5% * 5) ≈ $683.10
