Answer:

the box value is  $ 0.5

Step-by-step explanation:

if we don't want to get confused what we can do is 2 equations, one that represents the relationship between the box and the candy, and another that represents the money

x = candy

y = box

x = y + 19

x + y = 20

we replace in the second equation the value of x by (y + 19)

x + y = 20

(y + 19) + y = 20

y +y = 20 - 19

2y = 1

y = 1/2

y = 0.5

we replace in the first equation the value of y by its value

x = y + 19

x = 0.5 + 19

x = 19.5

so the candy value is $ 19.5 and the box value is  $ 0.5

Answer:

c = a - 16

Step-by-step explanation:

Given

a = b + 12 ( subtract 12 from both sides )

a - 12 = b

Substitute b = a - 12 into b = c + 4

a - 12 = c + 4 ( add 12 to both sides )

a = c + 16  ( subtract 16 from both sides )

c = a - 16

If $396 is invested at an interest rate of 13% per year and is compounded continuously, how much will the investment be worth in
Vilka [71]

Answer:  First option is correct.

Step-by-step explanation:

Since we have given that

Amount invested = $396

Interest rate = 13% per year

Time = 3 years

We will use the "Exponential growth formula" i.e.

A=Pe^{rt}

Here,

P denotes Principle amount

r denoted rate of growth

t  denotes number of years,

So, it becomes

A=396e^{0.13\times 3}\\\\A=396e^{0.69}\\\\A=\$584.88

Hence, First option is correct.
