Question

The cost of 5 bangles and 2 rings was $143. Each ring cost 3 times as much as each bangle. Find the total cost of a bangle and a ring.

Answer 1

Step-by-step explanation:

Cost of 5 rings = 39045

Cost of 10 bangles = 78090

Step-by-step explanation:

Cost of 2 rings and 4 bangles,

2 : 4 = 46854

Or,

6 = 46854

1 = \frac{46854}{6}

6

46854

1 = 7809

Cost of 2 rings = 2\times 78092×7809

= 15618

Then,

Cost of 5 rings = \frac{15618}{2}\times 5

2

15618

×5

Cost of 5 rings = 39045

Thus,

Cost of 10 bangles = 7809\times 107809×10

Cost of 10 bangles = 78090
