Question 172168
a bank teller is counting his money and notices that he has an equal number of tens and twenties and $147 in other bills. if the total value of the bills he has is 1,167, how many tens and twenties does he have
----------------------
Let # of tens be "x"; value is 10x dollars
Since # of 20's is "x": value is 20x dollars
---------------------
Value EQUATION: 10x + 20x + 147 = 1167 dollars
30x = 1020
x = 34 (# of tens ; also # of 20's)
