Answer:
D) P = 8b - 1000
Step-by-step explanation:
Think about it,
First off
If they spent 1000 from just buying the cookies. When you buy something you lose money. So that's -1000.
Secondly,
If they charged $8 per box that would cost an additional eight dollars each time a cutomer perchased a box. Another way to show addition is multiplication.
Ex if someone bought 7 box and 8 dollars each it could be shown as either:
1. 7 + 7 + 7 + 7 + 7 + 7 + 7 + 7
2. 8 + 8 + 8 + 8 + 8 + 8 + 8
3. 7 x 8 or 8 x7
So 8b - 1000 would make the most sense.
The three numbers are 12, 18 and 24
Arithmetic progression
Let the 3 number in arithmetic progression be:
a-d, d, a+d ...
If their sum is 3, then;
a-d+d+a+d = 3
2a + d = 3 ........... 1
If the sum of their squares is 11, then;
(a-d)² + d² + (a+d)² = 11
a²-2ad+d²+d²+a²+2ad+d² 11
2a²+3d² = 11 ....... 2
Solving the equations simultaneously, d = 6 and a = 12
First-term = 12
second term = 18
Thirs term = 24
Hence the three numbers are 12, 18 and 24
Hope this helps you!!!!!! :D
