First, you have to multiply 29,990x0.065 to find the sales tax, which is $1,949.35 Then, you just add $29,990 and $1,949.35 to find the total cost of the car including the tax which you get $31,939.35
Let the smaller one is x so the larger is x+1 x(x+1)=1332 x^2+x=1332 x^2 +x -1332 =0 (x - 36)(x + 37) =0 so x = 36 or x = -37 therefor the larger integer is either 37 or -36
