?

anonymous · Answer

$x$ is the price of the soda.

$$x + (x - 1.00) = 1.70$$

anonymous · Answer

What do you mean?

anonymous · Answer

$x - 1.00$ is the price of the pretzel, since the pretzel is $1 less than the price of the soda (which, you'll recall, is $x$).

This is an algebraic problem.  Can you solve the equation I typed above?

aripotta · Answer

p + s = 1.70
s = p + 1.00

using the substitution method:
p + p + 1.00 = 1.70

can you solve for p now?
