Step-by-step explanation:
600*.30=180
600+180=780
<span>Each ticket costs $10. He bought "x" tickets. Ticket cost = 10*x
Each bag of popcorn costs $5.
He bought "y" bags of popcorn.
Popcorn cost = 5*y
Service fee: $3
Total cost = 10x + 5y + 3 <= $75 is the inequality.
10x + 5y <= 72
If x = 4,
then 40 + 5y <= 72
5y <= 32
y <= 6.4
So y = 6 bags of popcorn.</span>
<span>Tangerine trees yield 50 pounds of fruit per acre.
</span>
Grapefruit trees yield 75 pounds of fruit per acre.
Let the number of <span>acres of tangerine = x
</span>
And <span>the number of acres of </span>grapefruit = y
The total produced <span>of fruit = 1,500
</span>
The equation which represents the total fruits of tangerine and <span>grapefruit is:
</span>
<span> 50 x + 75 y = 1500 →→(1)</span>
Now, to answer the given question, Is it possible for Sheila to have 15 acres of tangerine trees and 10 acres of grapefruit trees?
∴ x = 15 and y = 10
By substitution in (1) with x and y
∴ 50 * 15 + 75 * 10 = 750 + 750 = 1500
Which is agree with the total produced from Sheila's orchard.
So, the answer is :
Yes, it is <span>possible for Sheila to have 15 acres of tangerine trees and 10 acres of grapefruit trees.</span>
