Answer:
7
Step-by-step explanation:
We want to find the number 4-digit of positive integers n such that removing the thousands digit divides the number by 9.
__
Let the thousands digit be 'd'. Then we want to find the integer solutions to ...
n -1000d = n/9
n -n/9 = 1000d . . . . . . add 1000d -n/9
8n = 9000d . . . . . . . . multiply by 9
n = 1125d . . . . . . . . . divide by 8
The values of d that will give a suitable 4-digit value of n are 1 through 7.
When d=8, n is 9000. Removing the 9 gives 0, not 1000.
When d=9, n is 10125, not a 4-digit number.
There are 7 4-digit numbers such that removing the thousands digit gives 1/9 of the number.
Answer:
D is the answers for the question

Answer:
$11.32
Step-by-step explanation:
Greeting Cards = $1.5 x 2 = $3
Wrapping Paper = $2.29 x 3 = $6.87
Ribbon = $1.45 x 1 = $1.45
So now we must add the totals to figure out how much money Barbra spent in total.
$3 + $6.87 + $1.45 = $11.32
