Alice will do four games when until she rolls the fourth bowling ball, and the average score we need at the fourth roll is 145. We can’t get the answer now we can get the number which is the result of the all the number’s addition. So 145*4=580 will be the result.
So if we are finding the fourth number we can subtract the number we have to the whole number until fourth roll.
So 580-(139+143+144)= 580-326=254 will be the answer.
ANSWER: 254
