Answer:
Barett Sold 88 Tickets
Explanation:
To Start off we are told that the Total of tickets sold between Amelia (A) and Barrett (B) was 137.
Total = 137
Since Barett Sold 10 less than twice as many tickets as Amelia, we can make the following equation, where Barett is B and Amelia is A.
A + B = 137
A + (2A-10) =137 (Barett equalls 10 less than twice Amelia)
Now we can solve the equation for A
A + (2A-10) =137
3A - 10 = 137 (Combine Like Terms)
3A = 147 (add 10 on both sides)
A = 49 (divide by 3 on both sides)
Now that we have the amount of tickets that Amelia sold we can plug it in for B to find out how many tickets Barett Sold
(2A-10) = B
(2*49) - 10 = B
(2A-10) = B
98 - 10 = B
88 = B
