Len made the following purchases: a hammer for $8.29, lightbulbs for

$4.99, and curtain rods for $17.49. He paid 4% sales tax. Calculate
his total purchase.
a. $32
b. $30.77
c. $1.23
d. $31

To solve this problem, we need to first calculate the total cost of the items before tax is added:

$8.29 (hammer) + $4.99 (lightbulbs) + $17.49 (curtain rods) = $30.77

Now we need to add 4% sales tax to this amount:

$30.77 x 0.04 = $1.23

Finally, we add the tax to the original cost to find the total purchase:

$30.77 + $1.23 = $32

Therefore, the answer is (a) $32.
