.3 Evaluate two-variable equations: word problems

YJT
This equation shows how the number of cookies Mark can bake is related to the amount of flour he has.

c = 7f

The variable f represents the number of scoops of flour Mark has, and the variable c represents the number of cookies he can bake. With 6 scoops of flour, how many cookies can Mark bake?

cookies

1 answer

To evaluate how many cookies Mark can bake with 6 scoops of flour, we can substitute \( f = 6 \) into the equation \( c = 7f \).

Given:

\[ c = 7f \]

Now, substitute \( f \) with 6:

\[ c = 7 \times 6 \]

Calculating that gives:

\[ c = 42 \]

So, with 6 scoops of flour, Mark can bake 42 cookies.
