(-3f)^-3
So write it as a fraction
1/(-3f)^-3
Solve denominator
1/(-3)^3 f^3
1/(-27)f^3
Move neg in front of fraction and multiply 27by f^3
- 1/27f^3
Lets label hot dogs as 'h' and soft drinks as 'd'
6h + 4d = 13
3h + 4d = 8.50
We can solve by process of elimination.
Subtract the first equation from the second one.
We get:
3h = 4.5
Solve for h
<span>h = 1.5 </span>
<span>That means that the hot dog costs $1.50 which is answer choice </span>D.
<span>Hope that helps :)</span>
