Suppose the value R(d) of d dollars in euros is given by R(d)-d The cost P(n) in dollars to purchase and ship n purses is given
S_A_V [24]

<u>Corrected Question</u>

Suppose the value R(d) of d dollars in euros is given by R(d)=\dfrac67 d. The cost in dollars to purchase and ship n purses is given by P(n)=66n+23. Write a formula for the cost, Q(n) in euros to purchase and ship n purses.

Answer:

Q(n)=\dfrac67(66n+23)

Step-by-step explanation:

The value R(d) of d dollars in euros is given by R(d)=\dfrac67 d

Therefore:

R(1)=\dfrac67

T$hat is, 1  dollars =\dfrac67$ euros

The cost P(n) in dollars to purchase and ship n purses is given by:

P(n) = 66n+23.

Therefore, the cost, Q(n) in euros to purchase and ship n purses

=\dfrac67 \cdot P(n)\\Q(n)=\dfrac67(66n+23)

On a table what does quadratic, linear, and exponential mean?
salantis [7]
A quadratic equation is an equation with exponents and x's, for example 3x^2+4x+3 is a quadratic. and quadratics usually have two points it can cross the x axis. though that doesn't mean it always crosses twice. some quadratic equations can cross more then twice and some don't at all.

linear equations are simple. they always show a straight line on a graph.

And exponential are kind like quadratics, exponential always have an exponent but don't have multiple x intercepts. exponentials  are equations like the equation for compound interest rates (Initial Account Balance * (Interest Rates) ^ Time) it is exponentially growing using exponents.
