Charles has 2 2/3 ounces of seeds. He needs 4 4/5 ounces in order to complete the garden. How much more seeds he need?

yawa3891 [41]

Answer:

Charles need $3\frac{1}{5}$ more ounces of seeds.

Step-by-step explanation:

Given that:

Quantity of seeds Charles has = $2\frac{2}{3}$ = $\frac{8}{3}$ ounces

Quantity of seeds Charles need = $4\frac{4}{5} = \frac{24}{5}$ ounces

Let,

x be the number of remaining seeds Charles need.

x = Seeds needed - Seeds Charles already have

x = $\frac{24}{5}-\frac{8}{3}$

x = $\frac{72-24}{15}$

x = $\frac{48}{15}$

x = $\frac{16}{5}$

x = $3\frac{1}{5}$ ounces

Hence,

Charles need $3\frac{1}{5}$ more ounces of seeds.

Luther earned some money doing odd jobs last summer and put it in a savings account that earns 3% interest compounded quarterly

inysia [295]

The function we have to use in this case is

$m(t)=m_o\cdot(1+\frac{0.03}{4})^{4t}$

where mo is the initial amount of money. After 2 teats we get that

$\begin{gathered} m_0\cdot(1+\frac{0.03}{4})^8=800 \\ m_0\cdot1.06=800 \\ m_0=\frac{800}{1.06}\approx754.71 \end{gathered}$

SO he earned 755 approximately
