Lorenzo bought 3 pounds of grapes at $2.50 per pound, a gallon of milk for $4.25, and 2 boxes of cereal that originally cost $4 each but were on sale for $1.50 off. He wrote an expression to determine the total weight. 3 × 2.50 + 4.25 + 2 × (4 – 1.50) What is the first step in evaluating the expression? multiply 2 by 4 add 2.50 and 4.25 multiply 3 by 2.50 subtract 1.50 from 4

"Subtract 1.50 from 4"

Step-by-step explanation:

The expression is:

When we have a list of arithmetic operations, we can follow the PEMDAS rule. Which is:

P - Parenthesis

E - Exponents

M - Multiplication

D - Division

A - Addition

S - Subtraction

This is the order of operation.

Now, looking at the expression, we have to do "parenthesis" first. The expression does have parenthesis so we have to do:

(4 - 1.5)

which is equal to 4 - 1.5 = 2.5

From the answer choices, the first the step is:

"Subtract 1.50 from 4"

answer: -2+√x,-2-√x
