Answer:
A. There were more PS4 games than Blurays rented on this day
Explanation:
P - number of PS4 games rented
B - number of Blu-rays rented
We have:
+) P + B = 35 => P = 35 - B => 5P = 5 x (35-B)
+) 5P + 3B = 145
=> 5x(35-B) + 3B = 145
=> 175 - 5B + 3B = 145
=> 30 = 2B
=> B = 15
P = 35 - B = 35 - 15 = 20
As P = 20 > B = 15
=> The number of PS4 games rented was greater than the number of Blu-rays rented
=> There were more PS4 games than Blurays rented on this day
=> A is the correct answer while B is wrong
PS4 games is rented for $5.00
=> The total rental income for PS4 games on this day was: P x 5 = 5 x 20 = $100
=> Answer D is wrong
Blurays is rented for $3.00
=> The total rental income for Blu rays on this day was: B x 3 = 3 x 15 = $45
=> Answer C is wrong
