Step-by-step explanation:
In Kate's equation, 20 is the total number of tickets, 4 is number of tickets per ride, r is number of rides already ridden, and 4r is the number of tickets used
in Brian's equation, 5 is total number of rides Katie can ride and 5 - r is the number of rides left to ride
Suppose he invest x dollars in one account, y in the other
x+y=12,500
0.042x+0.062y=669.50
multiple the first equation by 0.042: 0.042x+0.042y=525
subtract this new equation from equation 2: 0.02y=144.50
y=7225
x=12500-7225=5275
Answer:
42.40
Step-by-step explanation:
Discount = Original Price x Discount %/100
Discount = 49.88 × 15/100
Discount = 49.88 x 0.15

Final Price = 49.88 - 7.482
Final Price = $42.40
