The answer is D. Because it is easier to add 9 and 2 and also 8 and 1.
A) 20% of 449 = 89.8
B) 449 - 100 = 349
C) 449 - 75 = 374. 10% of 374 = 37.4. 374 = 336.6
D) 449 - 50 = 399. 20% of 399 = 79.8. 399 - 79.8 = 319.2
Hope this helps! :D
Hey there!
To solve this expression, you must follow your orders of operations or PEMDAS (Parenthesis, Exponents, Multiplication and Division, Addition and Subtraction).
In the case of <span>5[3(14.5+7)-3]-7.4, you not only have parenthesis, but you also have brackets. To start, you would first simplify what is in the parenthesis:
</span><span>5[3(14.5+7)-3]-7.4
5[3(21.5)-3]-7.4
Now, simplify what is in the bracket, starting by multiplying 3(21.5) since multiplication comes before addition and subtraction:
</span><span>5[3(21.5)-3]-7.4
5[64.5-3]-7.4
5[61.5]-7.4
Now, multiply 5*61.5 since multiplication comes next:</span>
<span>5[61.5]-7.4
307.5-7.4
And finally, subtract what is left since it is your final operation remaining to get 300.1 as your final answer.
Hope this helps and have a marvelous day!

You add 10+16 which gives you 26
Peppermint to chocolate is 5:3, so5p=3c, and peppermints to gummies is 3:4, so 3p = 4g.
5p = 3c
*3 *3
15p = 9c
---------------
3p = 4g
*5 *5
15p = 20g
---------------
15p = 9c
15p = 20g
9c = 20g, so chocolates to gummies is 9:20.
