Answer 1

Answer:

C

Step-by-step explanation:

Let t = price of tomato plants

and p = price of pepper plants

3t + 4p = 21.50 ...... (1)

5t + 2p = 19.50 ..... (2)

Multiplying eqn. (2) by - 2

(5t + 2p) * (- 2) = (19.50) * (- 2)

- 10t - 4p = - 39

-10t - 4p = - 39

3t + 4p = 21.50

____________

-7t    = -17.5

t = 2.5

Putting t = 2.5 in eqn. (2), we get:

= 5 * (2.5) + 2p = 19.50

12.5 + 2p = 19.50

2p = 7

= 3.5

Price of one tomato and one pepper plant = 3.50 + 2.50

Answer 2

Answer:

c  tomato 2.5

pepper = 3.5

Step-by-step explanation:

Let t= the price of tomato plants

p  =the price of pepper plants

3t+ 4p = 21.50

5t+ 2p = 19.50

Multiply the second equation by -2

-10t -4p =-39

Add this to the first equation to eliminate p

-10t -4p =-39

3t+ 4p = 21.50

---------------------

-7t    = -17.5

Divide by -7

t = 2.5

Now find p

5t+ 2p = 19.50

5( 2.5) + 2p = 19.50

12.5+2p = 19.50

Subtract 12.5 from each side

2p =7

p =3.5

We want the price of 1 tomato and 1 p

3.5+2.5
