Answer

Explanation:

Step1: Find the new selling - price of a jacket

Since the percent increase from part a is 140% or 1.4 in decimal form. The cost of a jacket is $35. The selling - price of a jacket is $35\times1.4 = 49$.

Step2: Set up an inequality to find the number of jackets

Let $n$ be the number of jackets. We want the total sales to be at least $340$, so the inequality is $49n\geq340$.

Step3: Solve the inequality for $n$

$n\geq\frac{340}{49}\approx6.94$. Since the number of jackets must be a whole number, we round up to the next whole number.
