Myra is evaluating the expression –31.7 + 4.5x, when x = 2.1.

–31.7 + 4.5(2.1)

    –27.2(2.1)

    –57.12

What was Myra’s error?

Answer 1

-22.25

Explanation:

-31.7+4.5(2.1)

-31.7+9.45

-22.25

Answer 2

Myra didn’t follow the order of operations (sometimes referred to as PEMDAS, GEMDAS, or BODMAS); she should have multiplied the 4.5 and 2.1 before adding the -31.7
