For this case we have the following situation:
The monthly cost of a gym in the city is $ 3. The initial registration is $ 25. Write a mathematical expression that models the problem.
So we have to define variables:
x: number of months
y: total cost
The mathematical expression that models the problem is:
B. 90. The perimeter is 30+30+15+15=90
Sid and Libby are planning to sell pies at a local fair.
=> $200 to rent a table at the fair.<span>
=> $3.00 per pie </span>costs for ingredients, other supplies, baking, and packaging<span>
They plan to sell the pies for $8 each.
Let's find out how many pies will they be selling inorder to gain profit
=> 200 + 3.00(n) = 8(n), where n is the number of pie.
Let's try 40
=> 200 + 3(40) = 8 (40)
=> 320 = 320
</span>=> 200 + 3(41) = 8 (41)
=> 323 = 328
<span>Thus, in their 41st pie, they will get a profit
</span>
D is your answer
