Question

A bag cost $58 more than 2 identical wallets. Mrs Tan paid $632 for 2 identical
bags and 8 identical wallets. Find the total cost of 8 wallets.​

Answer 1

Answer:

8 Wallets cost 8 * 43 = 344 $

Step-by-step explanation:

The text provides us with the following system:

1. B = 2W + 58

2. 632 = 2B + 8W

Which can be re-evaluated to:

1.    B  - 2W = 58

2. 2B + 8W = 632

We multiply 1. with 2 and get:

1.  2B - 4W = 116

We then subtract 1. from 2. and get:

12W = 516 --(:12)--> W = 43

We then insert W = 43 into 1.:

B = 2*(43) + 58

--> B = 86 + 58 = 144
