2 petunias leave $6.50 on her wallet, and 8 leave $5.00. This means that 6 petunias cost $1.50, and that 1 petunia costs 25 cents.
.25 goes into 3.50 (the amount of money she has left in her wallet after buying 14 petunias) 14 times. 14 + 14 =28.
Ying Ying can buy 28 petunias at most.
Answer:
E. the product of seven and the difference of b minus two
Step-by-step explanation:
7(b-2)
seven is being multiplied by the difference of b minus 2
So this can be written as the product of seven and the difference of b minus two.
Reasons its not the other answer choices
A. two subtracted from the quotient of seven divided by b would be (7/b) - 2
B. seven added to difference of b minus two would be 7 + (b-2)
C. the quotient of seven divided by b minus two would be 7/(b-2)
D. two subtracted from seven times b would be 7b - 2

Answer:
The check digit is 7.
Step-by-step explanation:
Check digit can be calculated by the following way:
- Add all the digits except the check digit that is the last digit on the right side.
Total = 0 + 2 + 4 + 6 + 7 + 9 + 3 + 6 + 1 + 6 + 3
Total = 47
- Add the digits at odd starting from left, double this amount and finally add it with the total from step 1.
= 0 + 4 + 7 + 3 + 1 + 3
Sum = 18
Doubling the sum = 36
Adding it with the total from step 1, we get
Total = 36 + 47
Total = 83
- Subtract the last digit of the total from step 2 with 10, and this will be check digit.
Check Digit = 10 - 3
Check Digit = 7
33 = 88x
x = 33/88
x = .375 = 37.5 percent
