Answer:
$24.3
Step-by-step explanation:
Tip:
15% of 18 = 0.15 x 18 = 2.7
Cost of Dinner:
Tip + Cost of meal = total price
2.7 + 18 = 20.7
Money Remaining:
Starting value - Cost of Dinner = Amount remaining
45 - 20.7 = 24.3

1 1
1 2 1
1 3 3 1
1 4 6 4 1
1 5 10 10 5 1
1 6 15 20 15 6 1
1 7 21 35 35 21 7 1
1 8 28 56 70 56 28 8 1
1 9 36 84 126 126 84 36 9 1 (this is the row you use)
So, the seventh term of (3x + 2y)^9 will be 84xy
