I need help with this... How is solving a one-step equation similar to solving a one-step inequality? How are they different?
Could someone please help me? Thanks

T=  149s + 127v +275f

Step-by-step explanation:

We are given that :

s represent number of soccer sets

v represents number of volleyball sets

f represent the number of football

Cost of each soccer set is $149

So,Cost of s soccer sets = 149 s

Cost of each volleyball training set = $127

So,Cost of v volleyball sets = 127 v

Cost of each  football set = $275

So, cost of F football sets = 275 f

Let the total cost be T

So , the total cost T =   149s + 127v +275f

So, the expression represents the total amount of money the smiths will spend before sales tax based on the number of sports sets they buy :
