Please help me with Part A and B!

A. When Katina has $280 in her bank account, 4 months have passed. Plug 4 months into Malorie's bank account equation:

a = 50(4) + 100

a = 200 + 100

a = $300

B. Malorie's bank account changes at a greater rate. Katina's bank account amount increases by $20 each month, whereas Malorie's bank account increases by $50.

Ex: month 5

Katina has 300, 20 more than the previous month.

Malorie has 350, 50 more than the previous month
