GuDViN [60]
Hi there....

-6m - 8 = 24
-6m = 24 + 8
-6m = 32
m = 32/-6
m = -16/3

Sam Ana Maria were shopping for school supplies. Each purchased different quantities of the same notebook and thumb drive. Sam b
disa [49]

the cost of each notebook and thumb drive is $5 and $12 respectively .

<u>Step-by-step explanation:</u>

Here we have , Sam Ana Maria were shopping for school supplies. Each purchased different quantities of the same notebook and thumb drive. Sam bought 4 notebooks and 1 thumb drive for $32. Maria bought 3 notebooks and 2 thumb drives for $39. We need to find the  cost of each notebook and thumb drive. Let's find out:

Let the cost of each notebook and thumb drive be x & y respectively , So

Sam bought 4 notebooks and 1 thumb drive for $32.

With info following is equation below:

⇒ 4x+y=32   ....... (1)

Maria bought 3 notebooks and 2 thumb drives for $39

With info following is equation below:

⇒ 3x+2y=39 ............ (2)

Multiplying equation (1) by 2 and Than subtracting (1) by (2):

⇒ 2(4x+y)-(3x+2y)=2(32)-39

⇒ (8x+2y)-(3x+2y)=64-39

⇒ 5x=25

⇒ x=5

Putting x=5 in 4x+y=32 we get:

⇒ 4(5)+y=32

⇒ y=32-20

⇒ y=12

Therefore , the cost of each notebook and thumb drive is $5 and $12 respectively .
