The correct answer is $10$ . It’s given that the cost for the entire purchase was $$27$ after a coupon was used for $$63$ off the entire purchase. Adding the amount of the coupon to the purchase price yields $27 + 63 = 90$ . Thus, the cost for the entire purchase before using the coupon was $$90$ . It’s given that Nasir bought $9$ storage bins. The original price for $1$ storage bin can be found by dividing the total cost by $9$ . Therefore, the original price, in dollars, for $1$ storage bin is $\frac{90}{9}$ , or $10$ .
