The correct answer to this
problem is letter B. Remember we need to
give the best estimate. Letter A could work, but
let's do a little math to show how we arrived $2400.
You begin by rounding the total cost of groceries
a month to $200 because it is easier to use with
mental math.
Next, we know that there are 12 months in a
year. We could have rounded 12 months to 10 months
so it was easier to estimate in our head, but
if we look at what we have, $200 for each of
12 months, you should be able to multiply 2 x
12 and get a better estimate.
Therefore, $200 x 12 months
= $2400
You need to find the BEST estimate so be sure
to look over your choices and work with those
possible answers.
