A ring costs $36 more than a bracelet. the cost of the bracelet is 4/7 the cost of the ring. find the total of the two items.
avanturin [10]
So let's use some equations to represent the data [let R= cost of ring & B= cost of bracelet]

R= B + $ 36 .... (1)

B= \frac{4}{7} × R ... (2)

By using simultaneous equations to solve for B and R.
Substitute eq. (1) into eq. (2)

      B =  \frac{4}{7} × (B + $36)

      B = \frac{4}{7}B + \frac{144}{7}

     ( \frac{7}{7}  -  \frac{4}{7} ) B =  \frac{144}{7}

     \frac{3}{7} B =   \frac{144}{7}

⇒  B = $48

By substituting value of B into ea (1)

If R = B + $36
   
   R = ($48) + $36
     
      = $84

∴  <span> the total of the two items = R + B
                                             = $84 + $48
</span>                                             = $132
