Answer:
hotdog $1, and hamburger $2
Step-by-step explanation:
D-is hot dogs, H-hamburgers
7D +4H = 15
4D +7H = 18
we got 2 equations with 2 unknown so we can solve
7D +4H = 15 multiply by 7
4D +7H = 18 multiply by -4
49D +28H = 105
-16D -28H = -72 add the two equations
33D= 33 so D=$1
go back to the first equation:
7*1 +4H =15 gives us 4H = 15-7; 4H = 8 so H= $2
So, the population will always be 50 percent of the previous population counted.
4,500×1.50^x=y
4,500 is the population that it starts with, while 1.50 is telling that it is increasing by 50%. X is the number of years.
We are trying to find it in 88 years, so we should replace x with 4. Here is the reason, it doubles every 22 years and we are looking 88 years.
4,500×1.50^4= 22,781.25
There can't be .25 of a person, so the answer would be 22,781.
