2 answers:
Answer:
Step-by-step explanation:
We have been given that the radius of the gear, r, must be greater than 4 cm.
We can represent this information in an inequality as:
We are also told that the gear must not exceed 4.1 cm. We can represent this information in an inequality as:
Upon combining both inequalities, we will get:
Therefore, our required inequality is .

This question can be approached using the present value of annuity formula. The present value of annuity is given by 
, where: PV is the present value/amount of the loan, P is the periodic (monthly in this case) payment, r is the APR, t is the number of payments in one year and n is the number of years.
Given that the<span> financing is for a new road bike of $2,500 and that the bike shop offers a 13.5% APR for a 24 month loan.
Thus, PV = $2,500; r = 13.5% = 0.135; t = 12 payments (since payment is made monthly); n = 2 years (i.e. 24 months)
Thus,
