Pauline withdrew $7.50 from her savings account every day for 3 days. Which equation is the best choice to help her determine the total amount of money she withdrew? (5 points)

(7.50)(−3) = −22.50; she withdrew $22.50

(−7.50)(3) = −22.50; she withdrew $22.50

(−7.50)(−3) = 22.50; she withdrew $22.50

(7.50)(3) = 22.50; she withdrew $22.50

Answer 3

To find the product of two and five-eighths and negative two and three-fifths, we multiply the whole numbers and the fractions separately.

First, let's multiply the whole numbers: 2 x (-2) = -4.

Next, let's multiply the fractions: 5/8 x 3/5 = (5 x 3) / (8 x 5) = 15/40 = 3/8.

Now we have our two results: -4 for the whole numbers and 3/8 for the fractions.

Finally, we combine the results to form the final answer:

negative four and three-eighths (or -4 3/8)

Answer 4

To multiply (−4)(−2)(−5), we multiply the negative numbers together.

(−4)(−2)(−5) = 8(-5) = -40

The answer is -40.

Answer 5

To determine the total amount of money Pauline withdrew, we need to multiply the amount of money she withdrew each day by the number of days.

Pauline withdrew $7.50 each day for 3 days.

The correct equation to determine the total amount of money she withdrew is:

(7.50)(3) = 22.50; she withdrew $22.50

Therefore, the correct choice is: (7.50)(3) = 22.50; she withdrew $22.50.
