Answer:
this may help you.look it once.
F(x) as a piecewise function would be:
f(x) = ($3/lb)x, for 0≤x≤10,
= ($1.50/lb)x, for (10,20], and
= ($0.50/lb)x, for (20,40]
To the above must be added $7.50, [0,10] or $12, (10,40]
Answer:
2:5, 5:2
Step-by-step explanation:
Lets use 30 and 12. 12 divided by 30 is 0.4, which reduced is 2:5, or u can write 0.4. Thats oil to flour
But opposite numbers for flour to oil, bc of common sense.
Hope this helps(would be appreciated if you mark this answer brainliest bc need for lvl up. )
