    –31.7 + 4.5(2.1)

    –27.2(2.1)

    –57.12

What was Myra’s error?

Answer 1

Answer:

-22.25

Step-by-step 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
