Let (a)= no. Of Agnes' candy bars; and (b) = no. Of Betty's candy bars...."Agnes determined that she sold 8 more candy bars than Betty" means "(a=8+b)"..."Agnes and Betty sold a total of 348 " means "(a+b=348)".. Substitute "(a=8+b)" in the equation "(a+b=348)".. Solve : (8+b)+b=348... 8+2b=348...2b=340...b=170.. Therefore, Betty sold 170 candy bars.
