Question

A cell phone company offers two texting plans to its customers. The monthly cost, y dollars, of plan A is y= 0.14x + 5, where x is the number of texts.

Answer 1

Step-by-step explanation:

The question does not state expressly what we are expected to solve for,

but we can proceed with the definition of terms in the given equation, and solve for the monthly cost y assuming a particular value for x the number of text

The given equation is the same as the equation of a straight line

y= mx+c

Now comparing the given equation with the straight-line equation

we can see that the $5 is a flat fee paid monthly which is the constant term

say we set the number of texts sent in a month is 400.

we can calculate the monthly cost as

y= 0.14(400)+5

y= 56+5

y=$61

The monthly cost as a result of sending 400 texts is $61
