Simone has discovered a blow-out sale in the mall. The cost of 1 sweater, 3 shirts, and 2 pairs of pants is $100. The cost of 3 sweaters and 6 pairs of pants is $201. The cost of 8 shirts and
2 pairs of pants is $144. If x is the number of sweaters, y is the number of shirts, and z is the
number of pants, which system of equations can be used to determine the sale price of the
sweaters, shirts, and pants?
