Question

john wants to buy a new bike that costs $337 and he already has saved $ 103. Estimate to find about how much more John needs to save to buy the bike.

Answer 1

You could estimate the $337 to $335.
You could estimate the $103 to $105.
335 - 105 = 230.
$230 is therefore the estimated answer.
The exact answer is as follows:
337 - 103 = 234.
$234 is therefore the exact answer.
Hope I helped.
