here's the equation: x+x+(x+12)+ 1/2(x+12) =81
combine like terms
(x+x+x+1/2x) + (12+6) = 81
simplify
7/2x +18=
subtract 18 from both sides.
7/2x=63
multiply by reciprocal (aka 2/7)
x=18
18+12=30 so celia gave 30.
Hope this helps!

The equation that gives the cost y of renting a car for x days from Rent-All is; y = mx + c
An equation model that gives the cost y of renting a car for x days from Rent-All is the standard slope-intercept form of the equation of a straight line.
The standard slope-intercept form of the equation of a straight line takes the form;
y = mx + c.
where;
- y is the cost of renting a car
- m is the rate of change of the cost y of renting a car per day
- c is a constant usually a flat rate for renting the car.
The equation that gives the cost y of renting a car for x days from Rent-All is;
y = mx + c
PS: The constant, c may be equal to zero. in some cases.
