Answer:

Step-by-step explanation:

let the number be x

4 times = 4x

the sum of 4 times a number and 5 equals to 9

4x + 5 = 9

4x = 9 - 5

4x = 4

divide both sides by 4

x = 1

$\sf{m = \frac{1}{2} }$

$\sf{\purple{Explanation}}$

$\sf{m = \frac{y_{2}- y_{1}}{m_{2} - m_{1}} }$

$\sf{m = \frac{9- 3}{7- ( - 5)} }$

$\sf{m = \frac{6}{7 + 5} }$

$\sf{m = \frac{6}{12} }$

This means that now we have: $n + 10$

Multiplies by 3:

This means that now we have: $3(n+10)$

Gets 42:

tyrone opens an account at the local bank by depositing $50 of his birthday money. He continues to deposit $50 each month for 5

Pavel [41]

Answer-

The amount will be $8944.62 after 5 years.

Solution-

We know that,

$\text{FV of annuity}=P[\dfrac{(1+r)^n-1}{r}]$

Where,

P = Payment = $50 monthly

r = rate of interest compounded monthly= $3\frac{1}{4}=3.25\%=0.0325$

n = number of period = 5 years = 5×12 = 60 months

Putting the values in the formula,

$\text{FV of annuity}=50[\dfrac{(1+0.0325)^{60}-1}{0.0325}]$

$=50[\dfrac{(1.0325)^{60}-1}{0.0325}]$

$=50[\dfrac{6.8140-1}{0.0325}]$

$=50[\dfrac{5.8140}{0.0325}]$

$=50\times 178.8923$

$=8944.62$

Therefore, the amount will be $8944.62 after 5 years.
