At the product store you can buy four bags of bananas for 2084 how much would it cost if you were to buy 3 bags
Darya [45]

Answer:

1563

Step-by-step explanation:

x= 1 bag of bananas

so, 4x=2084

Divide 2084 by 4 to find how much 1 bag of bananas would cost. 2084/4= 521.

To find how much 3 bags of bananas would cost, multiply 521 (the price of one bag) by 3. 521x3= 1563

3 bags of bananas are $1563

Math help questions <br>​
Evgen [1.6K]

After 1 year, the initial investment increases by 7%, i.e. multiplied by 1.07. So after 1 year the investment has a value of $800 × 1.07 = $856.

After another year, that amount increases again by 7% to $856 × 1.07 = $915.92.

And so on. After t years, the investment would have a value of \$800 \times 1.07^t.

We want the find the number of years n such that

\$856 \times 1.07^n = \$1400

Solve for n :

856 \times 1.07 ^n = 1400

1.07^n = \dfrac74

\log_{1.07}\left(1.07^n\right) = \log_{1.07}\left(\dfrac74\right)

n \log_{1.07}(1.07) = \log_{1.07} \left(\dfrac74\right)

n = \log_{1.07} \left(\dfrac74\right) = \dfrac{\ln\left(\frac74\right)}{\ln(1.04)} \approx \boxed{8.3}
