Answer:

60%

Step-by-step explanation:

112:70*100= (112*100):70\\(112*100)=11200\\11200:70=160

so if 70 is 100%, 112 is 160%

and that is a 60% difference

Iteru [2.4K]

The value of f(2a) is 8a

<h3>What is a function?</h3>

A function can be defined as a rule or expression that shows the relationship between a dependent and independent variable.

From the information given, we have;

g(a) = 4a

Let's determine the value for f(2a)

a = 2a

Let's substitute the value of a as 2a in the function

g(a) = 4a

g(2a) = 4 ( 2a)

Multiply through

g(2a) = 8a

Thus, the value of f(2a) is 8a

marta [7]

Answer: p = 75 + 250

Equation of the situation, in slope-intercept form is given as .

Where,

b = y-intercept

m = slope

n = number of computers sold

p = total cost

All we need to find is the value of m and b.

Using two pairs from the table of values, (4, 550) and (6, 700):

Substitute n = 4, p = 550, and m = 75 in , and find the value of b.

Subtract 300 from each side

b = 250

Substitute m = 75, and b = 250 in

✅Equation that represents the situation would be:
