Question

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 by P(n)- 66n+23. Write a formula for the cost Q(n) in euros to purchase and ship n purses. It is not necessary to simplify Q(n) D

Answer 1

Corrected Question

Suppose the value R(d) of d dollars in euros is given by
`R(d)=\frac67 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)=\frac67(66n+23)`

Explanation:

The value R(d) of d dollars in euros is given by
`R(d)=\frac67 d`

Therefore:

`R(1)=\frac67`

`T$hat is, 1 dollars =\frac67$ 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

`=\frac67 \cdot P(n)\\Q(n)=\frac67(66n+23)`
