Answer:
She can buy 11 tokens
Step-by-step explanation:
8/4.40=x/6.05 (i set this up as a proportion. tokens/price=tokens/price)
4.40x=48.8 (cross multiplied)
x= 11 (divided both sides by 4.40)
Answer:Sorry, but I don't know ;(
Step-by-step explanation:
Multiply by 4 to get rid of fraction
4(18) = 4(x/4 + 7)
72 = x + 28
x = 44
Solution; x = 44
Pop ok you see so the answer here would be frantically elastic
For this case we have the following difference equation:

Applying separable variables we have:

Integrating both sides we have:

applying exponential to both sides:

For y (1) = 1 we have:

Thus, the particular solution is:

Whose domain is all real.
Answer: y = 0.2 * exp ((3/2) x ^ 2) Domain: all real numbers
