Answer:
Part a) 2.36 quarts
Part b) 47.2%
Step-by-step explanation:
Let
x ---> percentage of the resulting mixture that is antifreeze
Remember that
we know that
3 quarts of a solution multiplied by 0.22 (percentage in decimal form) plus 2 quarts of a solution multiplied by 0.85 (percentage in decimal form), must be equal to 5 quarts of a solution multiplied by x (percentage of the resulting mixture)
so
The linear equation that represent this situation is
solve for x
Convert to percentage
therefore
The percentage of the resulting mixture that is antifreeze is 47.2%
To find out how many quarts of antifreeze are in the resulting mixture, multiply the total quarts of the resulting mixture by the percentage in decimal form
So we know that the club sent out 4 times as many coupons to potential members as existing. This means we have a ratio of 4:1
To find out the totals we must add both sides of the ratio to get the total parts of the ratio. 4=1 = 5
Then we divide the total coupons by the total parts 165/5 = 33
We now know that each part of the ratio is worth 33 coupons. Then we multiply each side of the ratio by 33 to get the totals:
4 * 33 = 132 1*33 = 33
Since we know the existing members were the 1 side of the ratio the answer is C. 33
the answer for A. 1/4. 2/4=1/2 3/4
