Question 4: If a pound of tomatoes costs $2.54 in the United States, what would be the price of tomatoes in England, stated in Euros per kilogram. Assume that 1 US Dollar = 0.735455 Euros and that 1 kg = 2.205 pounds.

- 1.57 Euros per kilogram

Question 5: A box of candy contains five dark chocolates and five white chocolates. If you pick randomly and eat each candy after choosing it, what is the probability of choosing three dark chocolates in a row?

- 1/8 = 0.125
- 1/12 is approximately 0.083
- 3/50 = 0.060
- 25/144 is approximately 0.174

Question 1 - C

The price increased by $2, which is 20% of the original price of $10. So the ticket now costs the original amount (100%) plus another 20%, for a total of 120% of the old price.

Question 2 - A

Since the flooring it priced in square feet, change the room dimensions to feet. Since there are three feet in a yard, 7 yards by 4 yards is equal to 21 feet by 12 feet, for an area of 252 square feet. Multiply by the cost per square foot.

Question 3 - B

Clarence earns $20 X 8 or $160 per day. If he works 260 days a year, he earns $160 X 260 or $41,600 per year. $3 million ÷$41,600 per year ≈ 72 years

Question 4 - D

$2.54/ 1 pound x 2.205 lbs/1 kilogram x 0.735455 Euro/ $1 is approximately 4.12 Euro/kilogram

Question 5 - B

Since you eat the chocolate, there will be one fewer chocolate in the box each time as well as one fewer dark chocolate. 5/10 x 4/9 x 3/8 = 1/12
