Lee needs some school supplies. He will buy 3 notebooks for $1.29 each, 2 dozen
pencils at $3.45 a dozen and a box of pens for $14.85 a box. Lee estimates that he
will spend about $25 on these school supplies.
Is Lee's estimation reasonable? How much will he spend exactly?
If 3 notebooks are 1.29 each, that’s 3.87 on notebooks. two dozen pencils at 3.45 a dozen is 6.90. add 3.87, 6.90, and 14.85 for a total of $25.62. While Lee’s estimate was reasonable, it was a bit short.
