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?

Myra should have multiplied -31.7 and 2.1 first.

Myra should have multiplied 4.5 and 2.1 first.

Myra should have subtracted -27.2 and 2.1 first.

Myra should have added -31.7 and 2.1 first.
