Answer:
B. The original purchase total must be at most to $44 before the discounts are applied.
Step-by-step explanation:
Solve the inequality by adding $10, then dividing by 0.8.
0.8x -$10 ≤ $25.20
0.8x ≤ $35.20 . . . . . . . . add $10
x ≤ $35.20/0.8 . . . . . . . divide by 0.8
x ≤ $44 . . . . . . . . . the before-discount purchase must be at most $44
Answer:
3.5 m/hr
Step-by-step explanation:
2 + c = 5 -c c = speed of current
2 c = 3 c = current speed = 1.5 m/hr
your speed = 5 - 1.5 (or 2 + 1.5) = 3.5 m/hr
Answer:
In B) y = x/7 , the constant of proportionality is 7.
Step-by-step explanation:
Two quantities X and Y are said to be in proportion if and only if
X = kY or, 
,
where k = Proportionality Constant.
Here, 7 is the constant of proportionality. Then,
A . y = 14x
here, 
≠ 7
B . y = x/7
here, 
= constant of proportionality .
C. y = x
here, 
≠ 7
