Marie pays $19.75 per month for her phone service and spends an
average of $6.00 per month for long-distance calls. How much does her
phone service cost her in all each year?
a. $309
b. $91.75
c. $237
d. $312
First, we need to find how much Marie spends on her phone service and long-distance calls in one month:
$19.75 (phone service) + $6.00 (long-distance) = $25.75
To find out how much she spends in a year, we multiply this by 12 (the number of months in a year):
$25.75 x 12 = $309
Therefore, the answer is (a) $309.
To calculate the total cost of Marie's phone service each year, we need to add the cost of her monthly phone service and the cost of her monthly long-distance calls.
The cost of Marie's phone service per month is $19.75.
The cost of her long-distance calls per month is $6.00.
To find the annual cost, we multiply the monthly cost by 12 (the number of months in a year):
Cost of phone service per year = ($19.75 + $6.00) * 12
= $25.75 * 12
= $309
Therefore, the phone service costs Marie $309 per year.
The correct answer is (a) $309.
To calculate how much Marie's phone service costs her in a year, we need to add her monthly phone service cost to the cost of her long-distance calls.
Her monthly phone service cost is $19.75, and she spends an average of $6.00 per month on long-distance calls.
To calculate her yearly phone service cost, we multiply her monthly phone service cost by 12 (the number of months in a year): $19.75 * 12 = $237.
Now we add the cost of her long-distance calls for a year: $237 + $6.00 * 12 = $237 + $72 = $309.
Therefore, the correct answer is (a) $309.
