Question

Michael and Imani go out to eat for lunch.

Part A
If their food and beverages cost $25.30 and there is an 8% meals tax, how much is the bill?
Part B
If Michael and Imani add an 18% tip to the bill, what does their lunch cost in total?

Answer 1

A. The bill would be $27.32, plus tax

Step-by-step explanation:
1. We need to find 8% of 25.30
2. To do so, we need to cross multiply
3. 25.30/100 = x/8 (percents on the bottom, price on the top)
-multiply 25.30 by 8 to get 202.4
-divide 202.4 by 100 to get 2.024
4. Add the two together!
-25.30 plus 2.024 is is 27.32 (rounded)


B. The total cost of lunch would be $32.24 (plus tax and tip)

Step-by-step explanation:
1. We need to find 18% of 27.32
2. To do so, we need to cross multiply
3. 27.32/100 = x/18
-multiply 27.32 by 18 to get 491.76
-divide 491.76 by 100 to get 4.9176
4. Add 4.9176 and 27.32 to get 32.24 (rounded)



Hope this helps!

Answer 2

Part A: $27.32

Part B: $32.24

Step-by-step explanation:

Part A:

$25.30 is the cost, since we are increasing it by the 8% meals tax, we are going to do 25.3 * the decimal form of 8%, or 0.08, plus one so that we already have our 25.3 factored in. Which equals 25.3 * 1.08, which equals 27.324, which we round to $27.32.

Part B:

We take our $27.32 and we times it by 1.18 for the reason stated above, which equals 32.2376, which is rounded to $32.24.
