Question

Marco bought 10 gifts and spent $11.50. How many of each item did he buy if friendship bracelets cost $1.50 and stickers cost $1?

Answer 1

10*1 +1.50 = 11.50

Therefore he bought 10 stickers and 1 bracelet

Answer 2

Answer:

Bracelets=3. Stickers=7

Step-by-step explanation:

Let number of bracelets=x

Let number of stickers=y

ATQ,

Cost of 1 bracelet=1.50

Cost of 1 sticker=1

Total money spent=11.50

Total items bought=10

Therefore, x+y=10

Y=10-x (1)

Cost of bracelets=1.5*x=1.5x

Cost of stickers=1*y=y

Therefore,

1.5x+y=11.5

Y=11.5-1.5x. (2)

From (1) and (2) we get,

10-x=11.5-1.5x

1.5x-x=11.5-10

0.5x=1.5

X=1.5/0.5

X=3

Y=10-x

Y=10-3

Y=7

Hope this helps
