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 +

LiRa [457]

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

$42.3 = 9.8v + 22.7$

And now you need to solve for the number of visits ( $v$ )!

$19.6 = 9.8v$

$v=2$

So you can visit the museum a maximum of 2 times!
