Jim mails one package that weighs 3/8 pound and another that weighs 2/3 pound. What is the total
weight of both packages?

25/24 pounds

Step-by-step explanation:

If we want to find the total weight, we should add the weights together

3/8+2/3

To add, we need a common denominator

The least common denominator of 8 and 3 is 24

To get a denominator of 24, multiply 3/8 by 3/3, and 2/3 by 8/8

3/8*3/3=9/24

2/3*8/8=16/24

Now, we have a common denominator and can add

9/24+16/24

Add the numerators, and leave the denominator as 24

25/24=1 1/24= 1.04166666

The total weight for both packages is 25/24 pounds

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
