Today an exercise equipment store took 15% off the price of a treadmill, and for the next 2 days, it will take 15% off the previ
ous day's price. If the price of the treadmill yesterday was $4000, what will be the price of the treadmill 2 days from now? (5 points: Part I – 1 point; Part II – 1 point; Part III – 1 point; Part IV – 2 points)
To find the price of the treadmill, you can calculate the amount you will pay after each day and then multiply by the percentage that you will pay for each additional day.
You should use 85% (100% - 15%) as the part you will pay for a quicker calculation.
$4000 x 0.85 = $3400 (after the first day) $3400 x 0.85 = $2890 (after the second day) $2890 x 0.85 = $2456.50 (after third day)
<span>If the price of the treadmill yesterday was $4000, what will be the price of the treadmill 2 days from now? I interpreted this as the discount would be applied for 3 days.</span>
30° Here's why: Using the well-known Pythagorian theorem we can reckon how long the hypotenuse is: c^2=6^2+36*3 -> c=12 Knowing that sin(a)=a/c=6/12=0.5 the measure of the angle in degrees is 30° Hope could help :)
