Answer: 4in
Step-by-step explanation:
Diameter is the radius * 2. The radius is 2in. 2 * 2 = 4
Both still have the same profit. $2 for sandwiches and $3 for wraps. The only reason why there is a difference in the total amount is the change in number of sandwich or wrap sold in a given month. Therefore, next month's total sale is higher than last month's total sale making it safe to assume that the sale of sandwich or wrap is higher than last month's sale.

4000+20x=11000
20x=11000-4000
20x=7000
20/20x=7000/20
x=350 $tudents.

if you set both equations to a y = mx+b, you'll notice the slope is the same, meaning the lines are parallel to each other, thus they never meet.
