So she originally had to pay 149.99 so first let’s set up an equation

325 = 149.99 + 40x

So here we have the total she paid and x represents the amount of calls she made. Let’s try to simplify this one step further

325 (-149.99) = 149.99 (-149.99) + 40 x
175.01 = 40x

So now let’s solve to find the amounts of calls

175.01 (/40) = 40x (40)

4.37525 = x

This needs to be rounded DOWN so we get x = 4 because she spent LESS than the given amount

Hope this helped
