A certain prosthodontist specializes in implanting gold and silver teeth in his patients’ mouths. He charges $650 for a gold tooth and $325 for a silver tooth. If his total fees for implanting gold and silver teeth last week were $15,925 in total, and he implanted five more gold teeth than silver teeth, how many teeth in total did he implant over the week?
Correct answer: A
Explanation
Let g be number of gold teeth and s be the silver teeth. Writing the given in equation form:
650*g+325*s=15,625g=s+5
simplifying the equations : 2g+s=49 and g−s=5
solving for g and s gives, g=18 and s=13. So, total is 31
Answer is A
