John just purchased a new car with a value of $35,000. The car loses value at a rate of 7.5%. Which equation best represents this situation if y is the value of the car and x is the number of years he has owned the car?

a. y=35000(0.925)^x b. y=1.75(35000)^x c. y=35000(1.075)^x d. y=0.25(35000)^x e. y=35000(1.75)^x f. y=35000(0.25)^x g. y=1.075(35000)^x h. y=0.925(35000)^x

Mr. Ishimoto ordered x new math books and y new workbooks for his class. The total weight of the box of books cannot be more than 50 pounds. If each math book weighs 3.2 pounds and each workbook weighs 0.8 pounds, which inequality represents the maximum number of each type of book that can be shipped in a single box?

3.2x+0.8y≤ 60

3.2x+0.8y≤ 50

0.8x+3.2y≤ 60

0.8x+3.2y≤ 60

A snail starts on her trip from a pumpkin patch to a strawberry field. One hour and 36 minutes later, a turtle leaves the pumpkin patch for the strawberry field and arrives at the same time as the snail. The distance between the pumpkin patch and the strawberry field is 52 m. Find the speed of the snail if it moves 32 m/hr slower than the turtle.
