Hulk bought half dozen Takis for $7.50. Iron Man bought a dozen for $15.00. If Thor was to purchase two Takis from each shop, what would be the price difference for both shops.

the difference would be 15

Step-by-step explanation:

because he spent 15 at the 1st store because they sell half dozen bags for 7.50 and if he got 2 half dozen then thats 15 at the other store he bought 2 full dozen and so he spent 30 and to find the difference you have to substract 30-15 and you get 15

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
