Adam is 2 years old. his sister lina is 1 year less than 3 times his age. write a numerical expression for linas age

Step-by-step explanation:

Let's take it part by part.

" lina is 1 year less than..."  So this means a value that we get some other way -1.  So let's call it x-1 for now.  The next part tells us how to get x.

"3 times his age"  so now we have 3y-1, where y is Adam's age.  We know adam's age though.

3*2 - 1

6-1

5

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

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
