The number of seats sold cannot be negative, so you have
... x ≥ 0, y ≥ 0
The limits on numbers of seats must be observed, so you have
... y ≤ 2000
... x + y ≤ 3000
And the revenue constraint must be met:
... 35x + 50y ≥ 90,000
Together, these inequalties are ...
{x ≥ 0, y ≥ 0, y ≤ 2000, x + y ≤ 3000, 35x + 50y ≥ 90,000}
Hello!
The formula for finding area of a rectangle is length × width
<em><u>1st garden
</u></em>l = 10.25
<u><em /></u><em />w = 6.2
6.2 × 10.25 = 63.55
Area = 63.55 ft²
<em><u>2nd garden</u></em>
l = 20.5
w = 12.4
20.5 × 12.4 = 254.2
Area = 254.2 ft²
Divide the bigger area by the smaller area
254.2 ÷ 63.55 = 4
The answer to your question is b -1
