Answer 1

Cost of one cheap golf ball is $0.75 and one expensive golf ball is $2.00

Explanation:

Let,

x be the price of one cheap golf ball

y be the price of one expensive golf ball

According to given statement;

6x+4y=12.50 Eqn 1

4x+3y=9.00 Eqn 2

Multiplying Eqn 1 by 4

4(6x+4y=12.50)

24x+16y=50.00 Eqn 3

Multiplying Eqn 2 by 6

6(4x+3y=9.00)

24x+18y=54.00 Eqn 4

Subtracting Eqn 3 from Eqn 4

(24x+18y)-(24x+16y)=54.00-50.00

24x+18y-24x-16y=4.00

2y=4.00

Dividing both sides by 2

`(2y)/(2)=(4.00)/(2)\\y=2.00`

Putting y=2.00 in Eqn 1

6x+4(2.00)=12.50

6x+8.00=12.50

6x=12.50-8.00

6x=4.50

Dividing both sides by 6

`(6x)/(6)=(4.50)/(6)\\x=0.75`

Hence,

Cost of one cheap golf ball is $0.75 and one expensive golf ball is $2.00
