r(b) = 12b
c(b) = 4 + 3.3b
I think profit is revenue minus the cost, so p(b) = r(b) - c(b)
= 12b - (4 + 3.3b)
12b - 4 - 3.3b //Combine like terms
8.7b - 4
Answer: D

Answer:
idk
Step-by-step explanation:
The number of boats are 8; so, he needs a total of 8*126 gallons.
In order to get the partial products, first you have to decompose 126 in its hundreds, tens and ones, that is, 126 = 100 + 20 + 6. Then multiply each of this terms by 8, as follows
8*100 = 800
8*20 = 160
8*6 = 48
Finally you have to add the results of these multiplications, that is, 800 + 160 + 48 = 1008. Therefore, he needs 1008 gallons for all the boats.
Answer:
16/21 dresses
Step-by-step explanation:
3/4 · k hours: 4/7 · k dresses for any constant k
If we want 1 hour, then k will need to be 4/3
4/3 × 4/3 hours: 4/7 × 4/3
1 hour = 16/21 dresses
