Answer:
B.
Step-by-step explanation:
So there are 16 grams initally. Then, the amount of water decreases by 3.5%.
So first we must find 3.5% of 16. 3.5% in decimal form is 0.035, since you divide 3.5 by 100. Then, when you multiply 0.035 by 16, you get 0.56. Since the solution decreased by that percentage, you must subtract 0.56 from 16, which is 15.44.
Then the amount of water decreases by 4.25%. That in decimal form is 0.0425. You multiply it by 15.44, and it comes out to 0.6562. You subtract that from 15.44, not 16, since some of the water has evaporated. So you get 14.7838.
35 = 70%
If you divide 35 by 7, you will find what 10% of your maximum bid is.
35/7 = 5
5 = 10%
Multiply your value of 10% by 10 to get 100%.
5*10 = 50
Your maximum bid would be $50. You actually spend $35. To find the amount more you were willing to pay, subtract the two values.
$50-$35 = $15
Answer: You were willing to pay 15 more dollars than you did.
10% of 14.99 = 1.499 (round to the nearest 10= 1.50)
14.99-1.50= 13.49
Answer = 13.49
Answer:
y=8
Step-by-step explanation:
12(3+y)=5(2y+8)
⇒36+12y = 10y+40
⇒12y-10y=40-36
⇒2y=16
⇒y=8
499+49.99x=y
499 is the initial cost of the computer
49.99x means you pay 49.99 per game
y is the total cost
