When Sylvie verified the solution on a graph, the lines intersected at one point. What was her error? She forgot to put both equations in slope-intercept form. She made an arithmetic mistake in the last step. She found the incorrect value of x. She did not substitute the value of x into one of the original equations to find y.

D). She did not substitute the value of x into one of the original equations to find y.

Step-by-step explanation:

For those who have different answers, and I'm getting free points UuU!

total amount of money that he should pay if he has not used his duty free exemption is $98

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
