Jane is saving her money in order to purchase a new racing bike. she initially saves $3 and plans to double the amount she saves each month. the bike jane wants is $1,536 at the local bike shop. which equation represents this situation, and after how many months, t, will jane have enough money to purchase the bike

The equation is:

After

Step-by-step explanation:

This situation can be represented by an exponential growth equation of the form

Where a is the initial amount

b is the growth rate

t is the time in months

In this case the initial amount is $ 3. Then

if she initially saves $3 and plans to double the amount she saves each month then

The bike Jane wants is $1,536 at the local bike shop.

Then

The equation is:

Now we solve the equation for t

t=9 months. hope this helps

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
