a
Step-by-step explanation:
Answer: 
Step-by-step explanation:
By definition, the equation of the line in slope-intercept form of is:

Where m is the slope and b is the y-intercept.
Then, given the slope 2/5 and the point, (-10, -5), you can calculate the value of b by susbtituting and solve for it:

Substitute this value and the slope into the equation. THerefore, you obtain:

You take ten percent of 33, which is 3.3, and subtract it from the original price.
33-3.3=29.7 which means the final price is $29.70
