Mr. Lee mailed 3 packages. The greatest amount he paid to mail one of these packages was $3.60. The least amount he paid to mail one of these packages was $1.70. What could be the total amount Mr. Lee paid to mail the packages?

8.30

Step-by-step explanation:

Lee mailed 3 packages

If he paid 1.70 for 1 package and 3.60 for 2 package

= 3.60×2 + 1.70

= 7.2+1.70

= 8.9

If Lee paid 3.60 for 1 package and 1.70 for 2 packages

= 3.60 + 1.70(2)

= 3.60 + 3.4

= 7

Hence the price paid to mail the thee packages is 8.30 because it falls in between 7 and 8.9

a. $8.30

Step-by-step explanation:

Highest paid was $3.60 and lowest paid was $1.70. There is a middle package that cost less than $3.60 and more than $1.70.

= 3.6 + 1.7

= $5.30

This rules out option c because we have not added the price of the third package and it is already higher than option c.

Add the maximum twice:

= 3.6 + 3.6 + 1.7

= $8.90

If the second package was assumed to have the same cost as the highest paid, the total would still be less than options b and d which makes them both wrong.

Option a is the most feasible answer.
