Translate the problem situation to a system of equations. Do not attempt to solve.The Cudly College football team scored 60 times last season, some on seven-point touchdowns and some on three-point field goals. Altogether, the 60 scores accounted for 248 points. How many touchdowns and field goals did they score? (Let x represent the number of touchdowns and y represent the number of field goals.)
A. x - y = 60, 7x - 3y = 248 B. x + y = 60, 7x + 3y = 248 C. x + 3y = 60, 7x + y = 248 D. x + y = 248, 7x + 3y = 60
