Answer:
A=BQ
Step-by-step explanation:
In order to find an expression, you can use the definition of the dividend in a division:

where A is the dividend, B is the divisor, Q is the quotient (the result of the division) and R is the remainder of the division.
Let A represent the integer variable number of prizes and B represent the integer variable number of participants.
In this case R=0 and B≠0, therefore:
A=BQ
A is divisible by B if A can be written as an integer multiple of B. In other words, you have to find an integer number Q that multiplied by B produces A.
The first question is a and the second is a
Answer:
She paid 9% of sales tax
Step-by-step explanation:
The sale price of diamond = $375
Let x be percent of sales tax
So, amount of tax = 
So, Amount including tax = 375+3.75x
We are given that Bethany paid $408.75 for a pair of diamond stud earrings.

3.75x=408.75-375

x=9
Hence She paid 9% of sales tax
