Step-by-step explanation:
Gcf= 108
9 * 12
45/108 and 24/108
Let e = your earnings.
Let h = number of hours you work.
Since you earn $20 per hour, the amount you earn is the number of hours times $20, or 20h.
e = 20h
Each banner uses 40/9 4 4/9 so 40/9 = 4/40 Making the whole number of 4 and 5. I hope I helped. It’s a little hard to explain.

Answer: 25</h3>
==========================================================
Work Shown:
x = number of $2 coins
y = number of $10 coins
x+y = 43 coins total
x = 43-y
2x = value of just the $2 coins only
10y = value of all the $10 coins only
2x+10y = total value of all coins mentioned
This value must be greater than $278, so,
2x+10y > 278
2( x ) + 10y > 278
2(43-y)+10y > 278
86-2y+10y > 278
8y+86 > 278
8y > 278 - 86
8y > 192
y > 192/8
y > 24
The smallest y can be is y = 25.
We need at least 25 coins worth $10 each.
