College logo water bottles priced at $12 sell at a rate of 30 per week, but when the bookstore marks them down to $8, it finds that it can sell 45 water bottles per week. what is the price elasticity of demand for the water bottles?

The price elasticity of demand is 1. You determine price elasticity by dividing the percent change in quantity demanded (there was a 150% change from 30 to 45) by the percent change in price (there was a 150% change from $12 to $8). 150/150=1.

Secured loans are protected by collateral security. examples: title loans where the borrower uses the car title as collateral security interest rates are lower and repayments are longer therefore risk is low as a collateral security is given as guarantee to the bank in case of failure to pay the loanunsecured loans are not protected by collateral security but it is given on the creditworthiness of the borrower, trusting that she/he will pay on time. examples; payday loans is a short term loan where the borrower lends money from the bank and pays is back when the borrower receives his/her wages.interest rates are high and repayments are shorter. but the risk is high as no collateral security is given as a guarantee to the bank for payment of the loan
