Answer:
Tom spent $12 dollars on a hat.
Tom spent $84 dollars on Sneakers.
Tom spent $32 dollars on DVDs.
Tom spent $56 dollars on Video Games.
Tom spent $216 dollars on a Snowboard.
Using these totals, you can work out the answers!
(Also for question 10, the answer is $88)
Explanation:
First, we have to figure out how much percentage of $400 he spent on the Snowboard in the pie chart. To do that, we add the total percentage cost of the other items shown and subtract it from 100 (which would be the generic total of a pie chart). 8 + 21 + 3 + 14 = 46. So now 100 - 46 = 54. So he spent 54% of $400 dollars on a snowboard.
Now, to figure out how much money he spent on the other things, we have to convert the percentage to a decimal and then multiply it by the total he spent. (which is 400)
3% = 0.3 So, 0.3 x 400 = 12.
21% = 0.21 So, 0.21 x 400 = 84.
8% = 0.8 So, 0.8 x 400 = 32.
14% = 0.14 So, 0.14 x 400 = 56.
54% = 0.54. So, 0.54 x 400 = 216.
Tom spent $12 dollars on a hat.
Tom spent $84 dollars on Sneakers.
Tom spent $32 dollars on DVDs.
Tom spent $56 dollars on Video Games.
Tom spent $216 dollars on a Snowboard.
Now, we just have to add all the totals together to double check if we get $400.
12 + 84 + 32 + 56 + 216 = 400!
