Answer:
$685.30
Step-by-step explanation:
Her hourly pay is $15.40
Her overtime pay is 1.5 x $15.40 = $23.10
She works 37 normal hours = 37 x $ 15.40 = $569.80
She works 5 overtime hours = 5 x $23.10 = $115.50
Adding her normal + overtime = $569.80 + $115.50 = $685.30

1.2mL will be needed to make 50 mL of a 2% solution
<h3>Ratio and proportions</h3>
Ratio are written in form of fractions.
If 50mL is required for a 2% solution, hence;
50% = 2mL
0.05 = 2mL
In order to determine the required mL for a 30% solution, we will have;
30% =x
0.03 = x
Find the ratios
0.5/0.3 = 2/x
Cross multiply
0.5x = 2(0.03)
0.5x = 0.6
x = 0.6/0.5
x = 1.2mL
Therefore 1.2mL will be needed to make 50 mL of a 2% solution

Answer:
<h2>
</h2>
Step-by-step explanation:
Of 85% of cars sold where not black then 100-85% where black = 15%
let the number of cars sold be y
then 15%*y=300
y= 300 divided by 15%
= (300*100)/15
=2000
therefore 2000 cars were sold
