Think and practise Then, it reduced it by \( 30 \% \) because it wanted to go back to the original price. Let's check if this is correct: a) A computer originally cost \( € 1000 \). How much did it cost at each stage of the process? b) What is the percentage variation in relation 70 to the original price?

in deposited \( \$ 2700 \) into a savin te of \( 0,3 \% \). Find the amount in

A store sells \( Q \) units of a product per year. It costs \( d \) dollars to store one unit for a year. To reorder, there is a fixed cost of b dollars, plus c dollars for each unit. How many times per year should the store reorder, and in what lot size, in order to minimize inventory costs? Use the general solution to find how many times per year a store should reorder, and in what lot size, when \( Q=100, d=\$ 10, b=\$ 20 \), and \( c=\$ 14 \).

You deposit \( \$ 1000 \) each year into an account earning \( 3 \% \) interest compounded annually. How much will you have in the account in 25 years? \( \$ \)
