The membership dues at an exclusive club are $1,750 annually. After every year of membership, the dues are lowered by $75. Choose the equation below that gives the dues of members, Dn, in their 7th year of membership. A. Dn = $1,750 - $75n ; D7 = $1,300 B. Dn = $1,750 - $75(n - 1) ; D7 = $1,225 C. Dn = $1,750 - $75(n - 1) ; D7 = $1,300 D. Dn = $1,750 - $75n ; D7 = $1,225
