Answer 2

Let the paid amount for chains = x

According to the question,

$96.30 = 3($15.50) + x

=> x = $96.30 - $46.5 = $49.8

Thus, the 6 chains cost = $49.8

Therefore, cost of 1 chain = $49.8/6 = $8.3

Thereby, Clair's answer is unreasonable because the actual cost of each chain was $8.3 and not $0.83.
