Explanation:
#"the number of pieces made "color(blue)"varies directly "#
#"with the number of workers"#
#"let p "=" pieces made and w"=" workers"#
#rArrppropw#
#"to convert to an equation multiply by k the constant"#
#"of variation"#
#rArrp=kw#
#"to find k use the given condition"#
#"16 workers made 40 pieces"#
#p=kwrArrk=p/w=40/16=5/2#
#"equation is " color(red)(bar(ul(|color(white)(2/2)color(black)(p=5/2w)color(white)(2/2)|)))#
#rArrw=(2p)/5#
#"20 pieces "tow=(2xx20)/5=8" workers"#
#"25 pieces "tow=(2xx25)/5=10" workers"#
#"100 pieces "tow=(2xx100)/5=40" workers"#
