Question 1

If 100 grams of ice cream contains 13 grams of fat, how much fat is in 550 grams of ice cream?
A)2 grams
B)14 grams
C)34 grams
D)423 grams
E)71.5 grams

Accepted Answer

The amount of fat in 550 grams of ice cream can be found by setting up a proportion based on the given information: $ \frac{13 \text{ grams of fat}}{100 \text{ grams of ice cream}} = \frac{x \text{ grams of fat}}{550 \text{ grams of ice cream}} $. Solving for $x$ gives $x = \frac{13 \times 550}{100} = 71.5$ grams of fat.

Question 12

A solution contains 12 milliliters of alcohol and 16 milliliters of water. If another solution is to have the same concentration of alcohol in water but is to contain 32 milliliters of water, how much alcohol must it contain?
A)19 milliliters
B)17 milliliters
C)20 milliliters
D)24 milliliters
E)22 milliliters

Accepted Answer

The concentration of alcohol in the first solution is 12 milliliters of alcohol to 16 milliliters of water, or a ratio of 12:16. Simplifying this ratio gives 3:4. To maintain the same concentration with 32 milliliters of water, we scale the ratio up to match the new amount of water. Since 32 is 4 times 8 (the multiplier to scale 4 up to 32), we multiply the alcohol part of the ratio (3) by the same factor, 8, to get 24 milliliters of alcohol.

Question 13

A basketball player makes 6 of 9 free throws in the first game of the season. If she shoots with the same accuracy in the second game, how many of the 15 free throws she attempts will she make?
A)10
B)9
C)20
D)23
E)8

Accepted Answer

The player's shooting accuracy is 6/9, which simplifies to 2/3. If she attempts 15 free throws in the second game, she is expected to make 2/3 of them. Calculating 2/3 of 15 gives 10.
