Amy was asked to multiply and number by 8 and then add 5. instead, she added 8 to the number and then multiplied the result by 5. this gave her 2015

she did (x+8)*5

2015 = (x+8)*5

divide both sides by 5

403=x+8

x = 403-8 = 395

using same number if she followed instructions it would be

395*8 =3160+5 = 3165
