Question

Jose worked 2.5 hours more than William. Together, they worked a total of 22 hours.. William workwd n hours.. A) h+5=22, B) h +(h+2.5)=22 C)h+(h-32.5)=22 D) h+2.4=22

Answer 1

jose worked j hours

wiliam worked w hours

jose worked 2.5 hours more than wiliam means j=2.5+w

togeter (sum) they worked 22hrs, so j+w=22

if we subsitute 2.5+w for j in the 2n equation we get

(2.5+w)+w=22, which matches equation B except they used h for william?

if we solved, we get w=9.75hrs so j=12.25hrs
