Question

The price of a 3D rectangle wall mirror is 14.50 dollars. Alice wants to buy 10 such wall mirrors. How much will she have to pay?

• A. 14.50 dollars
• B. 1.450 dollars
• C. 72.50 dollars
• D. 145.0 dollars

Answer 1

The correct option is D 145.0 dollars

Cost of a 3D rectangle wall mirror = 14.50 dollars

Cost of 10 such wall mirrors = 14.50 $\times$ 10

To multiply 14.50 with 10, we have to move the decimal point by one place to the right. Hence, we get:

Cost of 10 such wall mirrors = 145.0 dollars
