The price of 5 pencils and 2 books is Rp26,000.00, while the price of 3 pencils and 4 books is Rp38,000.00. If the price of 1 pencil is denoted by a and the price of 1 book is denoted by b, what is the correct system of linear equations that represents the problem above?

• 5a + 2b = 26,000 and 4a + 3b = 38,000

• 5a + 2b = 26,000 and 3a + 4b = 38,000

• 2a + 5b = 26,000 and 3a + 4b = 38,000

• 2a + 5b = 26,000 and 4a + 3b = 38,000
