Mario makes 6 free throw shots out of his first 10 attempts. What is the least number of consecutive shots Mario must make toincrease his overall percentage from 60% to at least 70%?1 shot4 shots10 shots14 shots
Question
Answer:
Answer:4 shotsStep-by-step explanation:Currently he makes: 6/10 = 60%
Letting x = additional free throws to make 70%, we can apply
(6 + x) / (10 + x) = 70%
Solving for x:
(6 + x) / (10 + x) = 7/10
cross multiply:
60 + 10x = 70 + 7x
3x = 10
x = 3 1/3
Since he can not make 1/3 of a shot, the least number of consecutive shots to get to 70% would be 4.
