Answer:
240
Step-by-step explanation:
If we get 10% off, we still have to pay 100-10 = 90%
Let x be the original price
x *90% = 216
.90x = 216
Divide each side by .90
.90x/.90 = 216/.90
x =240
The original price is 240

Step-by-step explanation:
Since he needs to make 2 appetizers per person, the variable "p" needs to go with the "2".

Answer:
13
Step-by-step explanation:
The perimeter is calculated by multiplying the sum of width and height with 2
2*(4x-2+7x+9) = 300 solve inside the parenthesis
2*(11x+7) = 300 multiply inside the parenthesis with 2
22x + 14 = 300 subtract 14 from both sides
22x = 286 divide both sides by 22
x = 13
Number 13 is c. Figure D
Number 14 is b. Figure D
