Answer:

We have the constraint 12x + 8y = 1800 to solve

x and y both have to be positive (she can't work negative hours)

If we choose x = 100 then we have 1200 + 8y = 1800

8y = 1800 - 1200 = 600

y = 75

We know this works because 12 * 100 + 75 * 8 = 1800 which is what she needs.

Answer:

Answer is 49

Step-by-step explanation:

Add all the ratios up you get 21 so then you divide 147 by 21 thus giving you 1 ratio = 7 respectively, and we know the ratio of the red is 7 because it's stated red, blue, and green -> 7,6,8. So then 7 * 7 = 49. And to confirm you can do (7*7)+(6*7)+(8*7) which should equal 147
