The lunch platter at one restaurant cost $7. write an equation that shows the total cost, c, of p people buying the lunch platter? i’m am not sure how to factor the variables into the equation.

c = 7p

Step-by-step explanation:

If 1 person buys the platter, the bill is c = 1 × $7.

If 2 people buy the platter, the bill is c = 2 × $7.

If 3 people buy the platter, the bill is c = 3 × $7.

(Do you see the pattern yet?)

If "p" people buy the platter, the bill is c = p × $7.

We ususally say "c is in dollars" and drop the "$" sign from the equation. When p is multiplied by 7, we conventionally write it as 7p.

... c = 7p

investment b is an ordinary annuity with $3,909.64 in the account after one year.

step-by-step explanation:

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
