Answer:
87.5
Step-by-step explanation:
Anoosha multiplied 0.7 times 1250 incorrectly kinda daft from Anoosha tbf
So,
The length is always 1.5 times the width.
l = 1.5w
lw = 24
lw = 54
lw = 96
Or, we could put it this way:
1.5w(w) = 24
1.5w(w) = 54
1.5w(w) = 96
So,
1.5w^2=24
1.5w^2=54
1.5w^2=96
Dividing both sides by 1.5, we get:
w^2 = 16
w^2 = 36
w^2 = 64
And solving for the only logical dimension, we get:
w = 4
w = 6
w = 8
And their corresponding lengths:
l = 1.5(4) = 6
l = 1.5(6) = 9
l = 1.5(8) = 12
So a few lengths could be:
(l,w)
(6,4)
(9,6)
(12,8)
Of course, there are infinite solutions.
Answer:
$5,376
$47,376
Step-by-step explanation:
Given :
Price of current model = $42,000
Percentage increase in price = 12.8%
Price increase in dollars :
12.8% of $42000
0.128 * $42000
= $5,376
Price of the next model :
Price of current model + increase in price
$42000 + $5376
= $47,376
