Question

7 T-shirt’s and a hat cost 47 pounds and 5 T-shirt’s and a hat cost 35 pounds how much is it for one hat and one T-shirt’s

Answer 1

Answer:

one hat and one T-shirt’s cost is 11 pounds

Step-by-step explanation:

7 T-shirt’s and a hat cost 47 pounds

5 T-shirt’s and a hat cost 35 pounds

LET ,  T = one T-Shirt's cost  ; H = one hat's cost

so, 7T + H = 47                                        

or, H = 47 -7T

AND      5T+H = 35

or. 5T+47-7T=35

or, -2T = 35-47 = -12

or, T = 6

now, H = 47 - 7T = 47 -42 = 5

So, H = 5

one hat and one T-shirt’s cost = T+H = 6+5 =11 pounds

Answer 2

Answer:

10

Step-by-step explanation:

Let no. of tshirts =x

no. of hats=y

therefore, A.T.Q

7x+y=47

5x+y=35

- - - [BY USING ELIMINATION METHOD]

2x =12

x=6

putting value of in above equation

7(6) + y=47

42+y=47

y=5

therefore, price of one tshirt=6

price of one hat=5
