Answer 2

$\sf \: Number \: of \: sheep \: in \: the \: herd \: = \: 80 \\ \\ \sf \: Number \: of \: sheep \: lost \: is \: 20 \: so \: 80 \: - \: 20 \: = \: 60 \: sheep \\ \\ \sf \: Number \: of \: sheep \: joined \: is \: 30 \: so \: 60 \: + \: 30 \: = \: 90 \: sheep \\ \\ \sf \: Number \: of \: sheep \: in \: the \: herd \:now \: is \: 90 \: sheep.$
