Question

Langston will pay $575 to three different credit cards: Expert Card, Passport, and US Speedy. She will pay three times as much to Expert Card as US Speedy since it has a higher balance. She also expects the Passport payment to be only 15% of the total of the other two payments. How much will Langston pay towards the Passport credit card balance?

Answer 1

Answer:

$75

Explanation:

Let, the payment made towards US Speedy credit card be 'U'

Therefore,

According to the question:

Payment made towards Express credit card, E = 3U

Total for the two cards = U + E

= U + 3U

= 4U

also,

Payment made towards passport credit card = 15% of 4U

= 0.15 × 4U

= 0.6U

Given: Total payment made = $575

Therefore,

E + U + 0.6 U = $575

or

3U + U + 0.6U = $575

or

4.6U = $575

or

U = $125

Hence,

Payment made towards passport credit card = 0.6U

= 0.6 × $125

= $75
