1. 14 reams of paper every 3 weeks is equivalent to 14/3 = 4.67 reams of paper each week.
2. If the recipe calls for 3 tablespoons of kernels, and Jennie uses 10 tablespoons, then she needs 10/3 = 3.33 times the amount of butter. So she needs 1/2 x 3.33 = 1.67 cups of butter.
3. If 2/3 of the tickets sold were adult tickets, then 1/3 were children's tickets. The theater sold 345 x 1/3 = 115 children's tickets. If adult tickets cost $13.95 each, then children's tickets cost 2/3 x 13.95 = $9.30 each. Therefore, the theater made 115 x 9.30 = $1069.50 from the sale of children's tickets.
4. Sales tax of 7.25% on a $199.00 purchase is 199 x 0.0725 = $14.42. Therefore, Louisa's total bill is 199 + 14.42 = $213.42.
5. The sales tax on a $105.79 food cost is 105.79 x 0.09 = $9.52. Therefore, the total cost including tax is 105.79 + 9.52 = $115.31. The pre-tax amount is $105.79, and a 20% tip on that amount is 105.79 x 0.20 = $21.16. Therefore, the total cost including tax and tip is 115.31 + 21.16 = $136.47.
6. The percent error is calculated by taking the absolute value of the difference between the predicted time and the actual time, dividing it by the predicted time, and then multiplying by 100 to get a percentage. So, (|53 - 60| / 60) x 100 = 11.67%.
7. A cylinder holds 6,750/1000 = 6.75 liters.
8. A container holds 34,065/3785 = 9 gallons.
9. An airplane travels about 900 x 0.62 = 558 miles per hour.
10. The scale factor is calculated by dividing the enlarged side length by the original side length. So, 8/3 = 2.67 is the scale factor Leo used to create the photograph.
