A menswear store is having a sale: "Buy one shirt at full price and get another shirt for 35% off." If Ezra buys two shirts, each with a regular price of $10, how much money will he save?
| $3.00 | |
| $0.50 | |
| $2.50 | |
| $3.50 |
By buying two shirts, Ezra will save $10 x \( \frac{35}{100} \) = \( \frac{$10 x 35}{100} \) = \( \frac{$350}{100} \) = $3.50 on the second shirt.
If a car travels 60 miles in 2 hours, what is the average speed?
| 35 mph | |
| 30 mph | |
| 25 mph | |
| 55 mph |
Average speed in miles per hour is the number of miles traveled divided by the number of hours:
speed = \( \frac{\text{distance}}{\text{time}} \)A menswear store is having a sale: "Buy one shirt at full price and get another shirt for 50% off." If Ezra buys two shirts, each with a regular price of $37, how much will he pay for both shirts?
| $55.50 | |
| $49.95 | |
| $18.50 | |
| $42.55 |
By buying two shirts, Ezra will save $37 x \( \frac{50}{100} \) = \( \frac{$37 x 50}{100} \) = \( \frac{$1850}{100} \) = $18.50 on the second shirt.
So, his total cost will be
$37.00 + ($37.00 - $18.50)
$37.00 + $18.50
$55.50
If a mayor is elected with 89% of the votes cast and 46% of a town's 10,000 voters cast a vote, how many votes did the mayor receive?
| 4,094 | |
| 2,714 | |
| 3,036 | |
| 4,048 |
If 46% of the town's 10,000 voters cast ballots the number of votes cast is:
(\( \frac{46}{100} \)) x 10,000 = \( \frac{460,000}{100} \) = 4,600
The mayor got 89% of the votes cast which is:
(\( \frac{89}{100} \)) x 4,600 = \( \frac{409,400}{100} \) = 4,094 votes.
What is the next number in this sequence: 1, 4, 10, 19, 31, __________ ?
| 37 | |
| 54 | |
| 46 | |
| 44 |
The equation for this sequence is:
an = an-1 + 3(n - 1)
where n is the term's order in the sequence, an is the value of the term, and an-1 is the value of the term before an. This makes the next number:
a6 = a5 + 3(6 - 1)
a6 = 31 + 3(5)
a6 = 46
