[Answer]Cathy has $12 + $25 = $37 after his father sent him money. Her mom sent her $25 x 2 = $50. Therefore, Cathy has $50 + $37 = $87. The answer is 87.

[Question]A blind cave scorpion survives by catching millipedes. It needs to eat lots of millipedes to survive: a total of 800 body segments every day. If it's already eaten one millipede with 60 segments and 2 millipedes that are twice as long, how many 50-segment millipedes does it need to eat to reach its daily total?
[Answer]First, the number of segments in the 2 millipedes that are twice as long is 60 segments * 2 = 120 segments. Then one can multiply the segments by the 2 millipedes to find the total number of segments: 120 segments / millipede * 2 millipedes = 240 segments. In total, we then find the scorpion has eaten one 60 - segment millipede in addition to the 3 millipedes above for a total of 60 + 240 = 300 segments. So, the number of segments it still needs to eat are : 800 segments - 300 segments = 500 segments. Thus, it needs to eat an additional 500 segments / 50 segments / millipede = 10 millipedes. The answer is 10.

[Question]Sean designs and sells patches. He orders his patches in a unit of 100 and is charged $1.25 per patch. If he turns around and sells all 100 patches for $12.00 each, what is his net profit?
[Answer]He orders 100 patches and they cost $1.25 each so the patches are 100 * 1.25 = $125.00. He sells each of the 100 patches for $12.00 each so he makes 100 * 12 = $1,200.00. He makes $1,200.00 selling patches and spends $125.00 to have them made so his net profit is 1200 - 125 = $1,075.00. The answer is 1075.

[Question]Two friends are racing three miles. The first one runs it in 21 minutes. The second one runs it in 24 minutes. If they keep up the same pace, how long combined will it take for them to run 5 miles each?
[Answer]
The first one runs a mile in 7 minutes because 21 / 3 = 7. The second runs a mile in 8 minutes because 24 / 3 = 8. The first one would finish 5 miles in 35 minutes because 5 x 7 = 35. The second one would finish in 40 minutes because 5 x 8 = 40. It will take 75 minutes in total because 35 + 40 = 75. The answer is 75.
