Which scenario reflects an annual inflation rate of 3%? a. in year 1, the price of a computer is $325.00. in year 2, the same computer costs $328.00. b. in year 1, the price of a soda is $0.75. in year 2, the same soda costs $0.78. c. in year 1, the price of a board game is $10.00. in year 2, the same board game costs $10.03. d. in year 1, the price of a sofa is $500.00. in year 2, the same sofa costs $515.00.

D is the correct option

Step-by-step explanation:

We want to determine which of the given scenarios reflects an annual inflation rate of 3%.

To get the new or inflated price, we will find 3% of the former price and add it to the former price. Looking at the scenarios,

A) In year 1, the price of a computer is $325.00. Applying 3% increase, it becomes

(3/100 × 325) + 325 = 9.75 + 325

= $334.75. This is higher than the cost in year 2

B) In year 1, the price of a soda is $0.75. Applying 3% increase, it becomes

(3/100 × 0.75) + 0.75 = 0.0225 + 0.75= $0.7725. This is lower than the cost in year 2

C) In year 1, the price of a board game is $10.00. Applying 3% increase, it becomes

(3/100 × 10) + 0.75 = 0.3 + 10= $10.3. This is higher than the cost in year 2

D) In year 1, the price of a sofa is $500.00. Applying 3% increase, it becomes

(3/100 × 500) + 500 = 15 + 500= $515

It corresponds to the price of year 2

So the correct option is D

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
