Answer:

the first error she made was that she used the wrong numbers to multiply by

Step-by-step explanation:

Answer:

Error: she replaced 36 with the unequaled value of 3+12.

Step-by-step explanation:

The first error made is 36 cannot be substituted with 3+12 because 36 doesn't equal 3+12. She might have been thinking 3(12)=36. She could have done 10+10+10+5+1 for 36 and did the following:

27(10+10+10+5+1)

270+270+270+135+27

(270+270)+(270+135)+27

(540)+(405)+27
