Here is a list of numbers -45,-21,-16,12 33 ,40. write down two numbers from the list below that have a difference of 29, work out the sum of all numbers in the list.

a) we want two numbers where the difference of them is equal to 29. Where the difference between the numbers a and b is = a - b

You can use brute force here, this is, try for every option and find the correct one.

-45 - (-21) = -45 + 21 = -24, that pair is not the correct option

-45 - (-16) = -45 + 16 = -29, well, here we find that the difference between these two numbers is 29 units, so the correct option here is -45 and - 16.

b) The summ of all the numbers in the list is:

S = -45 +(-21) + (-16) +12 +33 +40 = 3

So the total sum of the numbers in the list is 3

step-by-step explanation:

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
