Answer:
5:2
Step-by-step explanation:
divide then both my 3 to get 5 for 15 and 2 for 6
Answer:
The markup is the difference between the selling price and the cost price, divided by the cost price, then multiplied by 100 to get a percentage.
The difference between the selling price and the cost price is $15 - $9.38 = $5.62.
So, the percent of markup is ($5.62 / $9.38) x 100 = 59.91%.
Rounding to the nearest percent, we get 60%. So, Kerri is marking up the doll clothes by 60%.

The x-intercepts of the given function are (2.5, 0) and (-4, 0)
From the question, we are to determine the x-intercepts of the given function
The given function is
f(x) = –2x² – 3x + 20
To determine the x-intercepts of the function, we will determine its zeros
That is, we would solve
0 = –2x² – 3x + 20
This can be rewritten as
2x² + 3x - 20 = 0
Solve by factoring
2x² + 8x - 5x - 20 = 0
2x(x + 4) -5(x + 4) = 0
Then,
(2x - 5)(x +4) = 0
2x - 5 = 0 OR x +4 = 0
2x = 5 OR x = -4
x = 5/2 OR x = -4
x = 2.5 OR x = -4
Hence, the x-intercepts of the function are (2.5, 0) and (-4, 0)
