Jeff spent half of his weekly allowance playing mini golf. to earn more money his parents let him wash the car for $4. what is his weekly allowance if he ended with $12?

the weekly allowance of Jeff is $16

Step-by-step explanation:

Let x represent the weekly allowance of Jeff.

Jeff spent half of his weekly allowance playing mini golf. This means that the amount that Jeff spent playing golf would be

x/2. He has x/2 left.

To earn more money his parents let him wash the car for $4. This means that the total amount of money that he has left would be

x/2 + 4

If he ended up with $12, it means that

x/2 + 4 = 12

x/2 = 12 - 4 = 8

x = 8 × 2 = 16

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
