Answer:

$305

Step-by-step explanation:

You have to use the following formula to calculate the accrued amount:

A=P(1 + rt), where:

A= accrued amount

P= principal amount= $250

r= rate of interest= 11%

t= time period= 2 years

Now, you have to replace the values in the formula:

A=250*(1+0.11*2)

A=250*(1+0.22)

A=250*1.22

A=305

According to this, at the end of 2 years, Jess owes the bank $305.

Samantha sends her son, Barry, to a preschool center on certain days. The cost of preschool is $45 per day along with a fixed mo

MAXImum [283]

Answer:

Step-by-step explanation:

We are given fixed monthly charge = $70.

The cost of preschool per day = $45.

Number of days = d.

Total cost of d days = cost per day × number of days + fixed monthly charge.

Therefore, we get equation

880 = 45×d+70

Now, we need to solve the equation for d.

Subtracting 70 from both sides, we get

880-70 = 45d +70-70

810=45d

Dividing both sides by 45, we get

$\frac{810}{45} =\frac{45d}{45}$

18=d.

Therefore,<em> 18 days Barry attended preschool last month.</em>

<em>Therefore, correct option is D option.</em>

The product of 2 consecutive #s is 4160 what are the numbers?

KengaRu [80]

So the so the product of two consecutive numbers is 4160 or
x(x+1)=4160
distribute
x^2+x=4160
subtract 4160 from both sides
x^2+x-4160=0
find the factor (if you want to know how, just ask in the comments)
(x-64)(x+65)=0
so the answer is x could be 64 or -65
so the number that work are 64,65 and -65,-64
