Step-by-step explanation:
Answer: 4.5p + 40 = 112
Step-by-step explanation:
Let p represent the number of pairs of shoes that Roger must sell in a day to meet his daily earnings goal.
Roger gets $40 per day as wages and $4.50 as commission for every pair of shoes he sells in a day. This means that if he sells p shoes in a day, his total earnings for that day is expressed as
4.5p + 40
Since his daily earnings goal is $112, then the equation to determine how many pairs of shoes he must sell to meet his daily earnings goal is
4.5p + 40 = 112
Let's write this proportion of equivalent ratios in equation form and then plug in our two known values to determine our two unknown values:
(s1)2 : (s2)2 = A1 : A2
(10)2 : (7)2 = 100 : 49
Ratio of the Areas = 100 : 49
It is a right triangle, so we can use pythagorean theorem which states
a^2 + b^2 = c^2
Leg^2 + Leg^2 = Hypotenuse^2
9^2 + x^2 = 15^2
81 + x^2 = 225
x^2 = 144
x=12
