Suppose the purchase price of a dining room set is $950. If the sales tax is $47.50, what is the sales tax rate?

5%

Step-by-step explanation:

this question is really asking what percent of 950 is 47.5?

is/of = %/100

47.5 is the 'is'

950 is the 'of'

'r' is the 'what percent'

47.5/950 = r/100

cross-multiply to get:

950r = 4750

r = 5

5%

Step-by-step explanation:

Price x sales  tax rate = sales tax

950 x sales tax rate =47.50

sales tax rate =47.50/950

sales tax rate = .05 or 5%

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
