Norma spent $13.25 on school supplies. She bought 3 binders that cost $3.75 each and some paper. Which equation could be used to figure out the cost of the paper? A. 13.25 = 3.75 + n B. 13.25 = 3.75 – n C. 13.25 = 3 × 3.75 + n D. 13.25 = 3 × (3.75 + n) i suck at math ;-;
i believe the answer is C, 13.25 = 3 x 3.75 + n since she bought 3 binders that cost $3.75 each, it's 3.75 x 3. add that to n, the cost of the paper, and you have the total amount Norma spent, $13.25
