[Question]Janet pays $40/hour for 3 hours per week of clarinet lessons and $28/hour for 5 hours a week of piano lessons. How much more does she spend on piano lessons than clarinet lessons in a year?
[Answer]First find the total Janet spends on clarinet lessons per week: $40 / hour * 3 hours / week = $120 / week. Then find the total Janet spends on piano lessons per week: $28 / hour * 5 hours / week = $140 / week. Then subtract her weekly clarinet spending from her weekly piano spending to find the weekly difference: $140 / week - $120 / week = $20 / week. Then multiply the weekly difference by the number of weeks in a year to find the annual difference: $20 / week * 52 weeks / year = $1040 / year. The answer is 1040.

[Question]Barry wants to make a huge salad using only cucumbers and tomatoes. He will use a total of 280 pieces of vegetables. If there are thrice as many tomatoes as cucumbers, how many cucumbers will be used in the salad?
[Answer]Let c be the number of cucumbers and t the number of tomatoes. The total is the sum of the number of cucumbers and that of tomatoes, which is c + t = 280 piece of vegetables. Since there are thrice as many tomatoes as cucumbers, this means c = t / 3. Therefore 3 * c = t. The sum will therefore be c + 3 * c = 280 pieces of vegetables. This means that 4 * c = 280 vegetables. Therefore c = 280 / 4 = 70 cucumbers. The answer is 70.
