This is just an algebraic problem, the correct option is:
<em>"Myra should have multiplied 4.5 and 2.1 first."</em>
<h3>
How to evaluate an expression?</h3>
Here we want to evaluate the expression:
-31.7 + 4.5*x
in x = 2.1
This just means that we need to replace x by 2.1 in the given equation.
Now, what Myra does is:
-31.7 + 4.5*2.1 = -27.2*2.1
So she took the sum between -31.7 and 4.5 first, this is her mistake, you only would do that if the expression was:
(-31.7 + 4.5)*2.1
But in our expression:
-31.7 + 4.5*2.1
The first thing you need to solve is the product in the second term, so we get:
-31.7 + 4.5*2.1 = -31.7 + 9.45 = -22.25

X=popcorn
x - 3.50=drink
2x+ 4(x-3.50)=32.50
2x+4x-14=32.50
solve for x
Answer:
D. 4 7/8 is your answer
Step-by-step explanation:
What you do is since the |-4 7/8| is in the absolute values you just take it out and make it a positive and that is your answer.
|-4 7/8|=4 7/8 is your answer.
