The answer for this question is. Sam had to mix equal parts of the two chemicals for the experiment. When we say equal, the same in number or amount. If equitably, dealing fairly or equitably with everyone. If equation, a complicated situation or issue. So the right answer is equal.
the demand for tires is unaffected and effect on the supply of tires could increase, decrease, or stay the same.
An increase in the price of rubber would lead to an increase in the cost of producing tires. Rubber is an input required in the production of tires.
As a result of the increase in the cost of rubber, the supply of rubber would decrease. This would lead to a leftward shift of the supply curve. Equilibrium price would increase and quantity would decrease
As a result of the advance in technology, there would be an increase in the supply of tires. As a result, the supply curve shifts outward. Equilibrium price would decrease and quantity would increase
Taking these wo effects together, the demand for tires is unaffected and effect on the supply of tire is indeterminate
