If you deposit $1000 in a savings account with an interest rate of r compounded annually, then the balance in the account after 3 years is given by the function b(c)=1000(1+r)^3 where r is as a decimal. what is the formula for the interest rate, r, required to achieve a balance of b after three years? a. r=1+(cubroot of b)/10 b. r=-1+(cubroot of b)/-10 c. r=-1+(cubroot of b)/10 d. r=-1+10/(cubroot of b)

Acoffee shop orders at most $3,500 worth of coffee and tea. the shop needs to make a profit of at least $1,900 on the order. the possible combinations of coffee and tea for this order are given by this system of inequalities, where c = pounds of coffee and t = pounds of tea: 6c + 13t ≤ 3,500 3.50c + 4t ≥ 1,900 which graph's shaded region represents the possible combinations of coffee and tea for this order?
