Let the no. of $10 bills be x, the no. of $5 bills be 2x, and the no. of $20 bills be y.
<span>A cashier collects 124 bills => x + 2x + y = 124 => 3x +y =124
</span>totaling $920 dollars => ($10)(x) + ($5)(2x) + ($20)(y) = $920 => 20x + 20y = 920
Now you got 2 equations :
3x +y =124 &
20x + 20y = 920
3x +y =124 => y=124-3x
Then Sub y=124-3x into 20x + 20y = 920,
ie. 20x + 20(124-3x) = 920
20x + 2480 - 60x = 920
2480 - 40x = 920
2480 - 920 = 40x
1560 = 40x
x = 39
X/5 + x/2 =14
⇒ 2x/10 + 5x/10 = 14 (common denominator)
⇒ 7x /10 = 14
⇒ 7x* (10/10) = 14*10
⇒ 7x = 140
⇒ (7/7)*x= 140/7
⇒ x= 20
The final answer is x=20.

Given the previous length of the bedroom and the current scale factor, the length of the bedroom in the current scale drawing is 1008ft.
<h3>What is the length of the bedroom in the scale drawing?</h3>
Scale factor is simply a measure for similar figures, who look the same but have different scales or measures.
To get new dimension;
New dimension = scale factor × current dimension
Given that;
- Current length of the bedroom = 9ft
- Current width of the bedroom = 11ft
- Scale factor = 112
- New length of the bedroom = ?
New dimension = scale factor × current dimension
New length of the bedroom = 112 × 9ft
New length of the bedroom = 1008ft
Therefore, given the previous length of the bedroom and the current scale factor, the length of the bedroom in the current scale drawing is 1008ft.
