A store has issued two different coupons for its customers to use. One coupon gives customers $20 off their purchase price, and
the other coupon gives customers 35% off of their purchase. The store allows customers to use both coupons and choose which coupon to apply first. For this context, ignore sales tax. A. A customer purchases an item for $110 and asks the cashier to apply the "$20 off" coupon first, followed by the "35% off" coupon. What is the cost of the item after the two coupons are applied?
B. A customer purchases an item for $110 and asks the cashier to apply the "$20 off" coupon first, followed by the "35% off" coupon. Use function notation to represent the cost of the item (in dollars) after the two coupons are applied.

<span>C. Two times r equals the diameter of the circle. Pi is needed for all circle formulas, so you multiply by Pi since you are finding the circumference.
2r = d or, 2 radius = one diameter
</span>π is used in both circle equations: <span> 2</span>πr (circumference) πr² (area of circle)
