A sporting good store sells basketballs and footballs. Gavin pay $44 dollars for 3 basketballs and 2 footballs. Andrew pays $31 dollars for 1 basketball and 3 footballs. What is the price of 1 football

The price of 1 football = $ 7 and price of 1 basket ball= $10

Step-by-step explanation:

Let x = price of 1 football.

y = price of 1 basketball.

As per given,

Multiply 3 to (ii) , we get

Eliminate (i) from (iii)

Put this in (ii), we get

Hence,  the price of 1 football = $ 7 and price of 1 basket ball= $10

use the power rule  

( a b ) n = a n b n

to distribute the exponent.

apply the product rule to  

3 x 2 y 3 . ( 3 x 2 ) 2 ( y 3 ) 2

apply the product rule to  

3 x 2 . 3 2 ( x 2 ) 2 ( y 3 ) 2

raise  

3

to the power of  

2 . 9 ( x 2 ) 2 ( y 3 ) 2 multiply the exponents in   ( x 2 ) 2

.

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 2 ⋅ 2 ( y 3 ) 2

multiply  

2   by   2 . 9 x 4 ( y 3 ) 2

multiply the exponents in  

( y 3 ) 2 .

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 4 y 3

⋅

2

multiply  

3   by   2 . 9 x 4 y 6

the answer is a
