Hope you are able to understand the solution. :-D
12 cards : $0.25
8 cards : $0.15
Answer: 14 / 20 = 70%
Step-by-step explanation:
The slope of the line is 0.35
x = number of items sold
y = total price in dollars
Therefore,
using slope formula,
The slope is rise over run. The slope of a line is the measure of its steepness.
<h3>Slope equation:</h3>
where
y₂ = 3.85
y₁ = 2.45
x₂ = 11
x₁₁ = 7
Therefore,
m = 3.85 - 2.45 / 11 - 7
m = 1.4 / 4
m = 0.35
