The cost of an apple pie is $13 and a blackberry pie is $18.
<h3>How to find the cost?</h3>
Let A be apple pies and B be blackberry pies.
3A + 11B = $237
3A + 12B = $255.
On solving the quadratic equation, we get
-B = -18
Therefore,
B = 18
Substitute B in any one of the equations,
3A + 11*18 = 237
3A = 237 - 198
A = 39/3
A = 13
The cost of an apple pie is $13 and a blackberry pie is $18.

I feel like it’s either 1 or 2
Answer:
10 minutes
Step-by-step explanation:
The question is on volume/capacity
Volume of the tank is given by = l×w× d where l is length, w is width and d is the depth
l=16 in w= 24 in and d=15in
v=16×24×15 =5760 in³
<u>Time to fill tank</u>
Given that 600 in³= 1 min
5760 in³=?
=(5760×1) /600 = 9.6 min
The equation for the projected cost C is as follows:
where Co is the current cost, r is the rate of increase as a decimal and t is the time in years.
Plugging in the given values, we get:
