The answer is 104.
1/4 of 104 is 26, 104 - 26 = 78
78 - 7 = $71
A = 8B
A + B = 180
8B + B = 180
9B = 180
B = 20
A = 8 * 20 = 160

Step-by-step explanation:
basically i had the same question so yeah! and im a pro at math
So to start you need to add 7 and 4 to get 11
Then you divide 1650mL by 11 which gets you 150mL
You then times that by 7 to get the ratio of blue paint which is 1050mL and times 150mL by 4 to get the ratio of red paint which is 600mL
