55% of what number is 44
Serggg [28]
Mathematically speaking the question is:
55% * x = 44
Applying equation rules this becomes:
x= 44 : 55% which can be further translated as:
x= 44 / (55:100)
Let's move 100 and instead of making it divide with 55, multiply with 44 (rule of inversion), then solve the remaining operations:
x = (44 * 100) /55 =>X= 4400 / 55 =>x = 80

Kazeer [188]

The question is incomplete, the complete question is;

A factory produces 1,250,000 toys each year. The number of toys is expected to increase by about 150% per year. Which model can be used to find the number of toys being produced, n (in millions), in t years?

A. n= 2.5(1.5)/t, t cannot = 0

B. n= 1.5t^2 + 1.25

C. n= 1.5t + 1.25

D. n= 1.25(2.5^t)

Answer:

D. n= 1.25(2.5^t)

Step-by-step explanation:

This is an exponential growth problem. In mathematics, for an exponential growth problem;

P = Po(1 + r)^t

Where;

P= amount at time t

Po =initial amount

r= rate

t= time

In the context of the question we have;

n= 1.25(1 + 150/100)^t

n= 1.25(2.5)^t
