Answer:
Credit card B is better for you.
Step-by-step explanation:
To find the total amount of money you'll spend using card A:
($150 * 12) = $1800 (spent, so we'll add that to our total spent)
$1800 * 0.02 = $36 (gained, so we'll subtract that from our total spent)
$50 (spent, so we'll add that to our total spent)
Put these together and we get...
1800 - 36 + 50 = $1814 spent throughout the year
To find the total amount of money you'll spend using card B:
$150 * 12 = $1800 (spent)
1800 < 1814, meaning card B allows you to spend less (better)
