Accepted Solution
A:
Hello! So as far as we see, plan 1 is $34.99 a month. Plan 2 is $134.97 every 3 months, which would mean we pay quarterly. You know that there are 12 months in 1 year, so first, let's solve for the yearly cost of plan 1. Do this by multiplying the monthly cost by 12. 34.99 * 12 is 419.88. Plan 1 cost $419.88 per year. Let's solve for plan 2. It costs $134.97 every three months, which is quarterly. Because of this, we would only have to multiply that number by 4. 134.97 * 4 is 539.88. Plan 2 is $539.88 per year. Let's make the plans easier to compare.
Plan 1: $419.88 Plan 2: $539.88
By looking at the numbers, plan 1 is cheaper than plan 2, so Krystal should go with plan 1. In order to find out how much she will save, let's subtract both prices from each other. 539.88 - 419.88 is 120. There. Krystal will save $120 by choosing plan 1 over plan 2.
