Question

Richard bought a birthday cake, a set of cheese pizzas, and a sweet burger at the prices given below. Which of the following gives the standard form of the number equivalent to the money he has to pay?

• A. 100 + 20 + 7 = 127
• B. 100 + 70 + 2 = 172
• C. 10 + 20 + 70 = 100
• D. 100 + 2 = 102

Answer 1

The correct option is A 100 + 20 + 7 = 127

Price of the birthday cake = 100 dollars

Price of the set of cheese pizzas = 20 dollars

Price of the sweet burger = 7 dollars

This is equivalent to the expanded form of numbers:

100 + 20 + 7

To find the total money, we have to find the standard form of the above expression.

$⟹$ 100 + 20 + 7 = 127

This is the correct answer, and Richard has to pay 127 dollars.
