Question

Hi, need help with this qn. Tq!

____________

Cheryl had twice as many beads as Diana at first. Everyday, Diana used 8 beads and Cheryl used 6 beads to make necklaces. When Diana had used up  all her beads, Cheryl still had 70 beads left.  How many days did Diana take to use up all her beads?

Answer

This is a Before After question.

    After   transfer  Before   
Cheryl   70 + 6u 6u + 70  
Diana 0 + 8u 8u  
         

(6u + 70) / 2 = 8u / 1

6u + 70 = 16u

70 = 16u – 6u

10u = 70

1u = 70 ÷ 10 = 7 days
