Answer:
It comes with 13.8 ounces of crackers now.
Step-by-step explanation:
12 + 15% = 13.8
Answer:
Use 49 ounces of the 14% allow and 41 ounces of the 23% alloy.
Step-by-step explanation:
Each ounce of the 14% copper contains 0.14 ounce of pure copper.
Each ounce of the 23% copper contains 0.23 ounce of pure copper.
Each ounce of the 18.1% copper contains 0.181 ounce of pure copper.
Use x ounces of the 14% and y ounces of the 23% to make 90 ounces of 18.1% alloy.
x+y = 90
y = 90-x
0.14x + 0.23y = 0.181·90
0.14x + 0.23(90-x) = 16.29
0.14x + 20.7 - 0.23x = 16.29
-0.09x + 20.7 = 16.29
4.41 = 0.09x
x = 49
y = 90-x = 41
Use 49 ounces of the 14% allow and 41 ounces of the 23% alloy.

Answer:
75% voted
Step-by-step explanation:
you add the 75 to 19 to figure out the total amount of people in the club.
75+19=76
Then you divide the people who voted which is 57 by the total amount of people in the club which is 76
57/76=0.75
then you move the decimal two places to the left and you get 75%
