Jim is baking loaves of bread. He has 200g of flour in the cupboard, 100g of flour on the kitchen counter, and 100g in the pantry. If one loaf of bread requires 200g of flour, how many loaves can Jim bake? Give the rationale and then the answer.
Let's think step by step. Altogether, Jim has 200g + 100g + 100g = 400g of flour. He can therefore bake 400g / 200g = 2 loaves of bread.. The answer is: 2.

Tire repair for each tire costs $7, plus another 50 cents for sales tax. If Juan needs all 4 tires repaired, how much is the final cost? Give the rationale and then the answer.
Let's think step by step. Juan pays 4 * 7 = 28 dollars for all four tire repairs. Juan pays 0.50 * 4 = 2 dollars in sales tax for all four tire repairs. Juan pays a total of 28 + 2 = 30 dollars.. The answer is: 30.

In mid-May, the depth of a river in Moreland is measured. By mid-June, the river is 10 feet deeper than mid-May. By mid-July, the river is three times deeper than mid-June. If the river is 45 feet deep in mid-July, how many feet deep was the river in mid-May? Give the rationale and then the answer.
Let's think step by step. In mid - June, the river is 45 / 3 = 15 feet deep. In mid - May, the river was 15 - 10 = 5 feet deep.. The answer is: 5.
