Answer:

2 tickets

Step-by-step explanation:

a + c = 5

9a + 4c = 30

let a = 5-c

substitute:

9(5-c) + 4c = 30

45 - 9c + 4c = 30

45 - 5c = 30

-5c = -15

c = 3

a = 2

AlekseyPX

Answer:

$260

Step-by-step explanation:

GIven

P=$250

R=4%

T=1 year

The total amount of simple interest is

A=P(1+rt)

substitute

A=250(1+0.04*1)

A=250(1.04)

A=250*1.04

A=$260

Hence the total amount is $260
