Answer: C. n = 4r + 50
Step-by-step explanation:
The equation is in the form: y =mx + c
y is the number of flowers used.
x is the row number.
Solving for m. Pick any two points. (1, 54) and (2, 58)
m = (Y₂ - Y₁) / (X₂ - X₁)
= (58 - 54) / (2 - 1)
= 4
Solving for c. Use a point to fill up the formula and find c; (1, 54)
y = mx + c
54 = 4 * 1 + c
c = 54 - 4
c = 50
Formula will therefore be;
y = 4x + 50
or;
n = 4r + 50
Answer:
$78.72
Step-by-step explanation:
To find 30% of the original value, we need to turn this percentage into a decimal or a fraction and then multiply it by the original value
- 30% is equivalent to 0.30,
, and
- So we can use either of these values. I will use 0.30 for simplicity
- ($262.40)(0.30) = $78.72 is the amount saved
