Answer:
The expression represents the total amount that Alexi needs to pay is T= 1.02A , where T is total amount and A is restaurant bill.
Explanation:
Given : Alexi’s restaurant bill is $58, and he wants to leave a 20 percent tip.
We have to find the expression represents the total amount that Alexi needs to pay.
Since, Alexi's restaurant bill is $ 58.
Also, she want to leave 20 % tip
So 20 % of her restaurant bill is 20% of 58

Thus, her total amount is 58 + 11.6 = $ 69.6
Alos, in expression it can be represented by
Total Amount to be paid = Amount + 0.02(Amount)
Mathematically, written as
T = A+ 0.20A
T= (1+0.02)A
T= 1.02A
The expression represents the total amount that Alexi needs to pay is T= 1.02A , where T is total amount and A is restaurant bill.
