Question

Lily has been keeping track of what she spends to eat out. The last week's expenditures for meals eaten out were $5.69, $5.95, $6.19, $10.91, $7.49, $14.53, and $7.66. The mean amount Lily spends on meals is $8.35. True False

Answer 1

The mean amount lily spends ($8.35) in a week is true according to the above statement.

The mean amount was calculated by adding up all the amounts she spent over the course of 7days (i.e $5.69+ $5.95+ $6.19+ $10.91+ $7.49+ $14.53+ $7.66). This addition gives us a total of $58.42.

The next step is to then divide the total amount ($58.42) by the number of days, i.e 7.

we then have, $58.42

7

Mean amount = $8.35.

The answer tells us that lily spent $8.35 evenly everyday for 7 days to accumulate $58.42.

you can go on to check how correct the answer is by simply multiplying $8.35 by 7.

Cheers.
