\nBut none of the options match the answer.
\nTherefore, the correct option is option E.<\/p>\n
\nSo, 22% of 364 –\u00a0x<\/span><\/span><\/span>x<\/span><\/span>\u00a0= 23
\nOr, 80.08\u00a0–\u00a0x<\/span><\/span><\/span>x<\/span><\/span>\u00a0= 23

\n797.7 – x = 514.9
\nx = 282.8
\nOption E is the correct answer.<\/p>\n
