Luis wants to change companies for his phone service. Company SaveMore charges $16 for the initial service plus $0.20 for every 1 text of use. Write an equation that represents the cost of the service, with the cost of the constant number of text, t added After how many texts will the two companies be the same charge for the service?

--- the equation of SaveMore company

Step-by-step explanation:

Given

SaveMore

Required

Determine the equation

Let

So, we have:

The equation for the second company is not given. So, the (b) part cannot be correctly answered.

A general solution to the (b) part is:

Assume the equation is:

Next, we equate both

i.e.

This gives:

Collect like terms

Divide by 0.2

Hence, the charges will be the same after 30 texts

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
