christopher is walking past a bike shop and looks inside. He sees some bicycles and some tricycles. He sees 32 seats and 77 whee ls. How many tricycles are in the shop.
2 answers:
A bicycle has 2 wheels and a tricycle has 3 wheels. Both have only 1 seat so he saw a total of 32 bikes.
Let "x" represent the number of bicycles and "y" represent the number of tricycles. <em>The solution below is using the substitution method.</em>
x + y = 32 → x = 32 - y
2x + 3y = 77 → 2(32 - y) + 3y = 77 → 64 - 2y + 3y = 77 → 64 + y = 77 → y = 13
Answer: 13 tricycles
Bicycles: 1 seat and 2 wheels Tricycles: 1 seat and 3 wheels So with this, we will be making a system of equations. One representing the amount of seats and one representing the amount of wheels. Let x = bicycles and y = tricycles:
With this, I will be using the substitution method. Firstly, subtract y on both sides of the first equation:
Next, substitute x in the second equation for (32 - y) and solve for y:
<u>In short, there are 13 tricycles.</u>
