Maria's birthday is in 22 days. Her friend Lilly wants to buy her flowers so she saves $2 each day until Maria's birthday. If a flower costs $4, how many flowers can she buy? Give the rationale and then the answer.
Let's think step by step. In 22 days she will have 22 days * $2 / day = $44. A flower costs $4 so she can buy $44 / $4 / flower = 11 flowers.. The answer is: 11.

To upgrade her kitchen, Amanda is changing out the doorknobs/pulls. She's replacing 18 cabinet knobs, which cost $2.50 each and 8 drawer pulls which cost $4.00. How much will the kitchen upgrade cost her? Give the rationale and then the answer.
Let's think step by step. She's replacing 18 cabinet knobs for $2.50 each for a total of 18 * 2.50 = $45.00. She's replacing 8 drawer pulls for $4.00 each for a total of 8 * 4 = $32.00. The cabinet knobs will cost $45.00 and the pulls will cost $32.00 for a total of 45 + 32 = $77.00 in upgrades.. The answer is: 77.

James gets a fleet of gas transportation vans. He gets 6 vans. 2 of them are 8000 gallons. 1 of them is 30% less than that. The remaining trucks are 50% larger than the 2 trucks. How many gallons can he transport? Give the rationale and then the answer.
Let's think step by step. His smaller truck is 8000 * .3 = 2400 gallons smaller. So it can transport 8000 - 2400 = 5600 gallons. There are 6 - 2 - 1 = 3 of the very large trucks. Those trucks are each 8000 * .5 = 4000 gallons larger. So they can transport 8000 + 4000 = 12000 gallons. So in total they transport 3 * 12000 = 36000. The 8000 - gallon trucks can transport 8000 * 2 = 16000 gallons. So in total he can transport 5600 + 16000 + 36000 = 57600 gallons.. The answer is: 57600.
