Maya wants to purchase a yearly membership to an indoor skateboard park. she'll also need to pay a set fee each time she visits the park. her parents want her to determine how much she'll spend at the park in one year. here's a formula for this scenario: t=m+cm t=total yearly cost m=cost of yearly membership c=cost for each visit n=number of visits per year

We are given the equation,

t = m + cn

We are asked to rewrite the formula to determine the cost of a yearly membership, m.

To transform this into the desired formula we want, all we have to do is to simply transfer the factor cn from the right to the left.

During a transfer, the mathematical sign of a factor changes to the opposite, that is:

+ becomes -     and       - becomes +

In this case, since cn has a sign of +, it becomes – if we transfer it. Therefore

t – cn = m

or

m = t – cn         (ANSWER)
