Dion puts seven tenths of his allowance into savings each month what fraction of his saving doesnt go in

S_A_V [24]

Answer:

$\frac{3}{10}$ of his allowance doesn’t go into Dion’s savings.

Step-by-step explanation:

We know that $\frac{7}{10}$ of Dion’s savings is going into his savings.

Since the denominator is “10” we know that $\frac{10}{10}$ is the fraction that represents all of his allowance money.

So, we would subtract $\frac{7}{10}$ from $\frac{10}{10}$ .

$\frac{10}{10}$ - $\frac{7}{10}$ = $\frac{3}{10}$

A cell phone company has a basic plan of $40 plus $0.45 for any minutes over 700. Before receiving his statement, John saw he wa

Darya [45]

Answer:

$718\ min$

Step-by-step explanation:

Let

x ----> the number of minutes

y ----> the total charge in dollars

we know that

For x>700 min

$y=0.45x+40$

For y=48.10

substitute

$48.10=0.45x+40$

Multiply by 100 both sides

$4,810=45x+4,000$ ----> equation without decimals

solve for x

$45x=4,810-4,000\\45x=810\\x=18\ min$

To find out the total minutes we need to sum

$18\ min+700\ min=718\ min$
