A driver travels 30 miles per hour for 3 hours and 25 miles per hour for 4 hours to deliver goods to a town every day from Monday to Saturday. How many miles does the driver travel in a week? Give the rationale and then the answer.
Let's think step by step. The driver travels (3 hours * 30 mph) + (25 mph * 4 hours) = 190 miles per day. From Monday to Saturday he travels in total 190 miles / day * 6 days = 1,140 miles in a week.. The answer is: 1140.

Aisha enjoys listening to music on her mp3 player. She starts with 500 songs on her mp3 player, then adds another 500 the week after that. She realizes her mp3 player has a large capacity for storing songs so she adds twice the amount she already had on her mp3 player. After a while, though, she decides that she doesn't like 50 of the songs and removes them. How many songs are on Aisha's mp3 player now? Give the rationale and then the answer.
Let's think step by step. Aisha starts with 500 songs + 500 songs = 1000 songs added to her mp3 player in the first two weeks. After that Aisha adds twice that amount to her mp3 player, 1000 x 2 = 2000 songs added. She now has 1000 + 2000 = 3000 songs on her mp3 player. However, she decides she wants to remove 50 of them, 3000 - 50 = 2950 songs on her mp3 player.. The answer is: 2950.

Five food companies sponsored a local food bank. Foster Farms donated 45 dressed chickens; American Summits donated twice the number of bottled water than the number of dressed chicken donated by Foster Farms; Hormel donated three times the number of dressed chickens that Foster Farms donated; Boudin Butchers donated one-third of the number of dressed chickens that Hormel donated; Del Monte Foods donated 30 fewer bottles of water than American Summits. How many food items did the companies donate in total? Give the rationale and then the answer.
Let's think step by step. American Summits donated 45 x 2 = 90 bottled waters. Hormel donated 45 x 3 = 135 spams. Boudin Bakery donated 135 x 1 / 3 = 45 sourdoughs. Del Monte Foods donated 90 - 30 = 60 canned fruits. Therefore, a total of 45 + 90 + 135 + 45 + 60 = 375 different food.. The answer is: 375.
