Answer:

88%

Step-by-step explanation:

(73+75+84+x)/4=80

x4 to both sides

73+75+84+x=80x4

73+75+84+x=320

232+x=320

x=320-232

x=88

Answer:

88

Step-by-step explanation:

80*4 = 320   320- (73 + 75 +84 ) = 88    we  can cross out 320/80 = 32/8 and 232/320  = 232 /4   (320/4) and divide each side by 4 = 58 / 80 then 29/40 = 40-29 = 11 then decimalise  /10 = 1.1   then multiply 80 * 1.1 = 88
