Jim is 2 years older than 3 times his little brother, Tommy. Together their ages add up to 18. How old are they both?
Answers
1. "Jim is 2 years older than 3 times his little brother, Tommy." J = 2 + 3T "Together, their ages add up to 18." J + T = 18 J = 18 - T, so 18 - T = 2 + 3T 4T = 16 T = 4, J = 14 (which is 2 more than 3 * T)
Melissa plans to purchase a pair of jeans for $39.95. She wants to bring enough money to pay for the jeans plus the sales tax, which is 8.25%. What is her total, including sales tax?
Answers
You have to calculate the 8.25% of $39.95, then add the numbers together. So: 8.25% of 39.95 = 3.3 (approximately) The total is 39.95 + 3.3 = 43.25
Another method is to simply calculate the 108.25% of 39.95, you can get this by multiplying 39.95 with 1.0825.
