Jason started with d dollars in his piggy bank. one week late, jason doubled the amount in his piggy bank. another week later, jason was able to add $20 to his piggy bank. at this point, the piggy bank had $50 in it. what is d?

Given, Jason had an amount of $d in the piggy bank.

After one week, Jason doubled the amount in the piggy bank.

So, after one week the amount in the piggy bank = $ = $(2d)

Another week later, Jason added $20 in the piggy bank.

So after another week, the total amount in the piggy bank = $

Given, that time the piggy bank had $50 in it.

So we can write the equation as,

To find the value of d, we will move 20 to the right side by subtracting it from both sides. We will get,

Now to find d, we will move 2 to the right side by dividing it to both sides. We  will get,

We have got the required answer.

The value of d = $15.

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!
