A 47 oz. jar of peanut butter sells for $$\$10.52$$. Jobe uses 2 oz. of peanut butter for each peanut butter sandwich they make. What would be the cost of the peanut butter if they made 7 peanut butter sandwiches? Round your answer to the nearest penny. Do not input the dollar sign. Only input the number. For example: $$3.42$$ Tia used $$7.95$$ CCF of water last month. The following is how Tia's water bill is calculated. How much will Tia's bill be for last month? Round your answer to the nearest penny. Do not input the dollar sign. Only input the number. For example: $$14.27$$ The following is a partial balance table for a simple interest account that deposits the interest every year. Find $$B(16)$$. Round your answer to.the nearest penny. Do not input the dollar sign. Input just the number. For example: $$1524.32$$ Thong opened a compound interest account. He made an initial deposit of $$\$1,280$$. The account pays him $$3.6\%$$ annual interest and is compounded annually. If Thong doesn't make any other deposits into this account, how many years will it take for the balance in Thong's account to be $$\$2,000$$ ? Here is the Balance Function for a compound interest account. $$B(t)=P?{\left(1+\frac{r}{n}\right)}^{n?t}$$ Round your answer to the nearest tenth of a year. Input only the number. For example: $$10.3$$ Eva opened a savings account with an initial deposit of $$\$846$$. They then deposit $$\$846$$ into that savings account at the end of every subsequent year. This savings account pays an annual interest rate of $$3\%$$ and is compounded annually. How much will Eva have in their account after 7 years? $$B(t)=p?\frac{\left({\left(1+\frac{r}{n}\right)}^{n?t}?1\right)}{\left(\frac{r}{n}\right)}$$ Round your answer to the nearest penny. Do not input the dollar sign. Only input the number. For example: $$2,153.23$$ $$71,06,4$$
