Quinn spent $16.49 for 3 magazineg and 4 packs of stickers. the magazines cos t $3.99 each and sales tax was 1.02. he .used a coupon for $1.50 off her purchase if each sheet of stickers is the same price how much did sheet cost?

Lets look at the information we have:-

$16.49 for 3 Magazines and 4 packs of stickers. 
$3.99 per magazine 
$1.02 sales tax
$1.50 coupon. 

Now lets subtract and take out magazines price.  

16.49 - 3.99 = 12.50
12.50 - 3.99 = 8.51
8.51 - 3.99 = 4.52
So the 4 packs of stickers TOGETHER cost $4.52. Now we are going to divide to find each price. 

4.52 ÷ 4 = 1.13
1 sticker sheet costs $1.13

CHECK OUR WORK:-

1.13 × 4 = 4.25.
We were RIGHT!!!

So, 1 sticker sheet costs $1.13.

Hope I helped ya!!
