The star television costs $750 more than the jupiter television. the two models cost $2,600 all together. sandra writes an equation to find the cost of the two models. if c represents the cost of the jupiter television, which of the following would be true when verifying the solution of the equation? check all that apply.
sandra substitutes c=925 into the equation c-(c+750)
=2600
sandra substitutes c=925 into the equation c+(c-750)=2600
sandra finds a true statement after substituting 925 into the equation.
sandra finds a false statement after substituting 925 into the equation.
when sandra evaluates the equation with c = 925, she subtracts 750 from 925. then, she adds that sum to 925. she finds that the value is not equal to 2,600.
when sandra evaluates the equation with c = 925, she adds 925 to 750. then, she adds that sum to 925. she finds that the value is 2,600.
