Answer:

d

Step-by-step explanation:

The answer is 1,000! For each digit you get 10 options: 0,1,2,3,4,5,6,7,8,9.

So if you were to have ten options for each of the three digits you can enter, you multiply all possibilities together. So 10 times 10 is 100. 100 times ten is 1,000.

(10 x 10 x 10 = 1000)

Answer:

1000

Step-by-step explanation:

We have 10 options for the first digit (0-9, inclusive)

We have 10 options for the second digit, too, because repetition is allowed.

We have 10 options for the third!

So!

10 * 10 * 10 = 1000 :))

26.50 × 20%
= 26.50 × 0.2
= 5.30
26.50 + 5.30
= 31.80
since charissa doesnt want to leave coins/pennies on the table, you would round it up.
31.80 would then epual 32.00 due to the tenths being above 5 (an 8)
