Answer:
- Let x and y represent the numbers of small and large cones sold daily, respectively
- 60 ≤ x ≤ 80
- 120 ≤ y ≤ 150
- 1.25x +2.25y > 350
Step-by-step explanation:
To answer the question, we need to be able to find the number of each type of cone that needs to be sold. For the purpose, it is convenient to define variables that represent those numbers. We have chosen to use the variables x and y to represent the number of small cones and the number of large cones, respectively ("Let" statement in above answer). One could use "s" and "l" as being more mnemonic, but "l" can be confused with a variety of other symbols, so we like not to use it.
The problem statement puts limits on the numbers of small and large cones sold, so our system of inequalities needs to reflect those limits. (We suspect these are not hard limits, but represent historical data. We doubt the shop would decline to sell more, and we can conceive of conditions under which they might sell fewer.)
The heart of the matter is that the profit from each type of cone must total more than $350 (per day). The problem statement requires the shop make a profit, not just break even, so we use the > symbol for profit, instead of ≥.

See above for the "Let" statement and the system of inequalities. (This problem does not require we solve them.)

Answer:
799
Step-by-step explanation:
Well, a Centimeter is 10 times bigger than a Milimeter.
So we can convert 9cm by multiplying it by 10
9 × 10= 90mm
SInce we know the length and width of the rectangle, we can now find the area of it, or "the space inside".
Area = length × width
Area = 90mm × 81mm
Area = 7290mm
