At the fish counter, salmon was selling for $9.60 a pound, whitefish for $7.20 a pound, swordfish for $8.40 a pound, and haddock for $6.90 a pound. Sasha bought 3/4 lb. of fish for $5.40. What fish did he choose?

5 answers

To find out which fish Sasha bought, we first need to determine how much she spent per pound based on the weight of fish she purchased.

Sasha bought 3/4 lb. of fish for $5.40. To find the price per pound, we divide the total cost by the weight she bought:

\[ \text{Price per pound} = \frac{\text{Total cost}}{\text{Weight}} = \frac{5.40}{\frac{3}{4}} = 5.40 \times \frac{4}{3} = \frac{21.6}{3} = 7.20 \]

So, the price per pound of the fish Sasha bought is $7.20.

Now, we can compare this price to the prices of the fish available:

  • Salmon: $9.60 per pound
  • Whitefish: $7.20 per pound
  • Swordfish: $8.40 per pound
  • Haddock: $6.90 per pound

Since the price per pound for the fish Sasha bought is $7.20, it matches the price of whitefish. Therefore, Sasha chose:

Whitefish.

On a quiz show, a contestant loses $12.50 in prize money for each wrong answer. One contestant has answered no questions right and 6 questions wrong. What is his balance of prize money?

To determine the contestant's balance of prize money, we need to calculate the total amount he has lost based on the number of wrong answers.

Given:

  • The contestant loses $12.50 for each wrong answer.
  • The contestant answered 6 questions wrong.

We can calculate the total loss as follows:

\[ \text{Total loss} = \text{Number of wrong answers} \times \text{Loss per wrong answer} = 6 \times 12.50 \]

Now, calculating that:

\[ \text{Total loss} = 6 \times 12.50 = 75.00 \]

Therefore, the contestant has lost a total of $75.00.

Since he has answered no questions right, his balance of prize money (assuming he started with $0) would be:

\[ \text{Balance} = 0 - 75.00 = -75.00 \]

Thus, the contestant’s balance of prize money is:

-$75.00 (indicating a loss).

What is the quotient when you divide −7/8 by - 1/5

To find the quotient when dividing \(-\frac{7}{8}\) by \(-\frac{1}{5}\), we can apply the rule that states dividing by a fraction is equivalent to multiplying by its reciprocal.

Here’s how the calculation looks:

\[ -\frac{7}{8} \div -\frac{1}{5} = -\frac{7}{8} \times -5 \]

Since the negatives cancel each other out, we can simplify this to:

\[ \frac{7}{8} \times 5 = \frac{7 \times 5}{8} \]

Calculating the multiplication:

\[ = \frac{35}{8} \]

Thus, the quotient when you divide \(-\frac{7}{8}\) by \(-\frac{1}{5}\) is:

\[ \frac{35}{8} \]

This is the final answer.
