This equation shows how the total cost of visiting the science museum as a member is related to the number of visits. c = 9.8v + 22.7 The variable v represents the number of visits to the science museum, and the variable c represents the total cost of those visits. What is the maximum number of visits a member of the science museum can make for a total cost of $42.30?

Well it's giving you what the cost is (42.3), so plug that in for [tex]c[/tex]:

[tex]42.3 = 9.8v + 22.7[/tex]

And now you need to solve for the number of visits ([tex]v[/tex])!

[tex]19.6 = 9.8v[/tex]

[tex]v=2[/tex]

So you can visit the museum a maximum of 2 times!
1st plug in 42.30 as C. 42.30=9.8v+22.7
2nd: subtract 22.7 from both sides to cancel it out. 42.30-22.7=9.8v+22.7-22.7
3rd: simplify. 19.6=9.8v
4th: divide by 9.8 so that it cancels out. 19.6/9.8=9.8v/9.8
5th: simplify. 2=V
