Answer: the equation is 4t = 3.60

The cost of 1 pound of banana is $0.9

Step-by-step explanation:

Let t represent the cost of 1 pound of banana in dollars.

Gavin paid for 4 pounds of bananas. This means that the total cost of 4 pounds of banana will be 4× t = $4t

He gave a $10 bill to the seller and he was given back $6.40. This means that the actual cost of 4 pounds of banana would be

10 - 6.40 = $3.60

Therefore,

4t = 3.60

t = 3.60/4 = $0.9

Let's first have a look at the admission fee, which is $6,- per person. 
This makes a total of $12,-
(Since 6 x 2 = 12).

Next up, the ride at the carnival. This costs c dollars.
This makes a total of 14c
(Since they have made a total of 14 rides (7 each), and we multiply it by 'c')

Finally the game boots, which costs g dollars a game.
Denise and Stacey played a total of 5 games, hence the total cost of the boots will be 5g.

The total cost will therefore be: 14c + 5g + 12
This makes the fourth answer (in your question) the correct answer.

Answer:

The answer is A, (1,2).

Step-by-step explanation:

Hope this helps!

8x-4(x+1) = 0

x =1

y = 1 + 1

y = 2

(x,y) = (1,2)

2 = 1 + 1

8 x 1 - 4 x 2 = 0

Simplify

2 = 2

0 = 0

Solution = (1 , 2)
