Answer:
1.875
Step-by-step explanation:
Data provided in the question:
Initial price, P₁ = $70
Final price, P₂ = $80
Initial supply quantity = $35,000
Final supply quantity = $45,000
Now,
Price elasticity of supply for tires =

on substituting the respective values, we get
Price elasticity of supply for tires =

or
Price elasticity of supply for tires =

or
Price elasticity of supply for tires = [ 0.25 ÷ 0.1333 ]
= 1.875
