The easiest way to answer this question is by rounding $5.99 and $7.99 to $6.00 and $8.00. Then multiply 3 by 6 and 5 by 8. 3 * 6 = 9 5 * 8 = 40 40 + 9 = 49. Now to find the exact answer, seeing as $5.99 is 1 cent away from $6.00 and $7.99 is one cent away from $8.00, we can do 3 * 1 = 3 and 5 * 1 = 5 3 + 5 = 8, we can see that $49 is 8 cents over. From there we subtract the 8 cents from the $49 and see that the amount she spent on downloads was $48.92.
