Write an equation that represents the total cost (in dollars) of the meal shown with a tip that is a percent of the check total. Let p​ represent the percent tip (as a decimal) and let c​ represent the total cost (in dollars).

with btw u said 100pts but it clearly says

i answerd and just got 10pts

no hate

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

this is the formula: v = the value of investment at the end of the time period

p = the principal amount (the initial amount invested)

r = the annual interest rate

n = the annual frequency of compounding (how many times a year interest is added)

t = the number of years the money is invested

^ means raise to the power of
