Mr. James bought 2 magazines for $9.99 each and 3 books for $12.60. If the sales tax is 7%, what was the total cost of Mr. James' purchases? Round to nearest cents.

$61.82

Step-by-step explanation:

2(9.99) + 3(12.60) = $57.78

Now that we know the total, let's find out how much is 7% of the total.

57.78 * 0.07 = approx. 4.04

Now, add that value to the total:

57.78 + 4.04 = $61.82

$61.82

Step-by-step explanation:

$9.99 x 2 = $19.98

$12.60 x 3 = $37.80

$19.98 + $37.80 = $57.78

$57.78 x 7 = 404.46

404.46 divided by 100 = 4.0446

$57.78 + $4.04 = $61.82
