The total number of stickers the 2 children had was 192 stickers.
Let x represent Mary initial stickers, y represent Gary initial stickers and z represent the total stickers.
x + y = z
They shared in the ratio of 5:3, hence:
x = (5/8)z
Mary gives 1/3 of her stickers to Gary to have 32 more stickers than her.
(1/3)x = (1/3)(5/8)z = (5/24)z
y + (1/3)x = (2/3)x + 32
Solving equation 1, 2 and 3 gives:
x = 120, y = 72, z = 192
The total number of stickers the 2 children had was 192 stickers.

The system won't have a unique solution when what appears to be two lines is really only one line. The coefficients in an equation for a line only matter in ratio; if we multiply them all by the same non-zero scalar we'll still have the same line, of course with an infinite number of points on it, our infinite number of solutions.
2x - y = 8
6x - 3y = 4a
We need these to be the same equation, meaning they have to have all the same solutions. So we have to figure out the factor to multiply the first equation by to get the second.
That factor is obviously 3 because 3(2x)=6x and 3(-y)=-3y. So we need the constants in the same ratio,
3(8) = 4a
24 = 4a
a = 6
Answer: B. 6
<h3>Given,</h3>
Number of shoppers per hour (during business hours) = 84
Time spent by each shopper (average) = 5 mins
<h3>Now,</h3>
→ 60 mins (1 hour) = 84 shoppers
→ 60 = 84
→ 84/60
→ 1.4
→ 1.4 × 5 = 7
→ 7 shoppers on an average, are waiting in the checkout line to purchase at the "Good Deals store"
