Darina [25.2K]

Let's assume

number of small notebooks =x

number of large notebooks =y

we are given

total number of notebooks =31

so, we get

$x+y=31$

now, we can solve for y

$y=31-x$

we have

Small notebooks cost $3.50 and large notebooks cost $5.00

she has $134 to spend

so, we get

$3.50x+5y=134$

now, we can plug y

$3.50x+5(31-x)=134$

$3.50x+5*31-5x=134$

$-1.5x+155=134$

$-1.5x+155-155=134-155$

$x=14$

now, we can find y

$y=31-14$

$y=17$

so,

number of small notebooks is 14

number of large notebooks is 17.............Answer

If you got a 1.25% interest rate how long would you need to invest $6000 if you wanted to earn $105 in interest

gavmur [86]

Answer:

1.4 years

Step-by-step explanation:

Use the formula for simple Interest:

$I = P * r * t$

Where I is the interest gained (in your case $105),

P is the principal (in your case $6000),

r is the annual interest rate in decimal form (in your case 0.0125)

and t is the time (in years) you need to find.

Therefore, we $105 = 6000 * 0.0125 * t = 75 * t\\t = \frac{105}{75} = 1.4 years$ solve for "t" in the following equation:
