[Question]: John gets $30 from his grandpa and 3 times that much from his grandma. How much did he get from the two grandparents?
[Answer]: His grandma gave 30 * 3 = $90. So he got a total of 30 + 90 = $120.
So the answer is 120.

[Question]: Jaymee is 2 years older than twice the age of Shara. If Shara is 10 years old, how old is Jaymee?

[Question]: Simon wanted to buy flowers that his mom could plant for Mother's Day. The garden center was offering 10% off all purchases. He bought 5 pansies at $2.50 each, one hydrangea that cost $12.50 and 5 petunias that cost $1.00 each. If he paid with a $50 bill, how much change would Simon receive back from his purchase?
[Answer]:
5 pansies at $2.50 each is 5 * 2.50 = $12.50. 5 petunias at $1.00 each 5 * 1 = $5.00. All total he spends 12.50 + 12.50 + 5.00 = $30.00. The sale is 10% off so 30 * .10 = $3.00. The purchase total now comes to 30 - 3 = $27.00. He pays with a $50 bill so 50 - 27 = $23.00.
So the answer is 23.
