Solving
25.3 = 6.2 + s
Solving for variable 's'.
Move all terms containing s to the left, all other terms to the right.
Add '-1s' to each side of the equation.
25.3 + -1s = 6.2 + s + -1s
Combine like terms: s + -1s = 0
25.3 + -1s = 6.2 + 0
25.3 + -1s = 6.2
Add '-25.3' to each side of the equation.
25.3 + -25.3 + -1s = 6.2 + -25.3
Combine like terms: 25.3 + -25.3 = 0.0
0.0 + -1s = 6.2 + -25.3
-1s = 6.2 + -25.3

Combine like terms: 6.2 + -25.3 = -19.1
-1s = -19.1
Divide each side by '-1'.
s = 19.1
Simplifying
s = 19.1
Answer: B) $47/week
===========================================================
Explanation:
Because the graph goes through the origin, we can simply divide the y value over the x value. Do so for any point on the diagonal line.
For example, picking (x,y) = (2, 94) leads to k = y/x = 94/2 = 47 being the constant of proportionality and also the amount of savings per week.
You can think of it like this:
2 weeks = $94 in savings
2/2 weeks = $94/2 in savings ... divide both sides by 2
1 week = $47 in savings
leading to the savings rate of $47 per week
----------
Side note: This linear equation is y = 47x. It is in the form y = kx with k = 47. It is a direct proportion equation. The constant of proportionality is also the slope. All direct proportion equations are linear and go through the origin.
<span>Tabia spent 15/24 of this week's allowance on gummy bears. She can calculate that by multiplying 3/4 times 5/6. To do that, she multiplies the top numbers of each fraction together (3 times 5 equals 15), and to get the top number of the fraction. Then she multiplies the bottom numbers together (4 times 6 equals 24) to get the bottom number.</span>
