At a college, the tuition increased by 10%. Let b be the former cost of tuition. Use the expression b + 1.10b for the new cost of tuition. Write an equivalent expression by combining like terms

Given:

At a college, the tuition increased by 10%. Let b be the former cost of tuition.

Use the expression for the new cost of tuition.

To find:

The equivalent expression by combining like terms.

Solution:

We have,

On combining the like terms, we get

Therefore, the required equivalent expression is 1.10b.

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years

step-by-step explanation:

answer:   x*94 +688*6   = 267*100

94x+4128=26700    

94x=22572     /94

x=240.128
