Question

Sally and Anne went to the movies. They each purchased a drink. They also bought one popcorn and one veggie cup to share. Each woman's total is modeled with this expression: 9+1.34+1/2(3.50+1.74) How would you simplify the expression? Explain your steps.

Answer 1

Answer: First, add the decimals in the parentheses. Next, multiply that number by 0.5. Finally, add all the decimal numbers.

Answer 2

12.91

Explanation:

We are told that Each woman's total is modeled with this expression:

9 + 1.34 + 1/2(3.50 + 1.74)

To solve this we will use the BODMAS acronym.

So the first operation will be to solve what's in the bracket to give;

9 + 1.34 + 1/2(5.14)

Let's now carryout the multiplication of the bracket to give;

9 + 1.34 + 2.57

Using the addition operation now gives us: 12.91
