Question 25

Marci deposited 280 dollars.

By calculating 7/8 of $320.00, we find that Marci deposited $280.00 in her checking account.

A) 120

This option is incorrect because 7/8 of $320.00 is significantly more than $120. If we calculate 7/8 of $320, we get $280, indicating that this option does not reflect the correct deposit amount.

B) 140

Option B is also incorrect as it underestimates the amount Marci deposited. The calculation of 7/8 of $320.00 is much greater than $140, thereby making this choice inaccurate.

C) 180

This choice is incorrect because $180 is still less than the actual amount deposited by Marci. The calculation shows that she deposited $280, which exceeds this option.

D) 240

Option D is incorrect as well, as $240 is lower than the correct calculation of 7/8 of $320. The actual deposit amount is $280, making this choice incorrect.

E) 280

This option is correct because it accurately reflects the calculation of 7/8 of $320. When performing the multiplication, 7/8 multiplied by $320 equals $280, confirming that this is the amount Marci deposited.

Conclusion

The correct answer is definitively $280 because it is the result of multiplying 7/8 by $320. All other options fail to represent the correct calculation, demonstrating a misunderstanding of how to compute the fractional part of the total amount. Thus, only option E accurately reflects Marci's deposit.
