Answer:

If a number is even, it's divisible by 2, i.e. 2 is a factor. If a number's digits total a number that's divisible by 3, the number itself is divisible by 3, i.e. 3 is a factor. If a number ends with a 0 or a 5, it's divisible by 5, i.e. 5 is a factor.

Answer:

Pretty sure the answer is $160.86

Step-by-step explanation:

you start off by multiplying 10.75 x 8 because that's how much he'll deposit at the end of an 8 week spand.

adding 86+138.22= 224.22

then you subtract 31.68 two times from that as he withdraws 2 times in the 8 weeks, giving you the answer of 160.86.
