Answer:
Sandwich sells for $4.76 .
Step-by-step explanation:
As given
It costs $2.80 to make a sandwich at the local deli shop.
To make a profit, the deli sells it at a price that is 170% of the cost.
170% is written in the decimal form

= 1.7
Thus
Sandwich selling cost = 1.7 × Cost of making
Put all the values in the above
Sandwich selling cost = 1.7 × $ 2.80
= $4.76
Therefore the Sandwich sells for $4.76 .
So if u were to use a calculator, which you probably might need, you would take the radius, square it by 3, multiply by 4 and then divide by 3.
Answer:
One solution
Step-by-step explanation:
6x+35=-6x+35
Add 6x to both sides (addition property of equality)
12x+35=35
Subtract 35 from both sides (subtraction property of equality)
12x=0
Divide both sides by 12 (division property of equality)
x=0
Therefore there is only one solution, 0.
