Find the constant of proportionality and the unit rate for the data table. Then write an equaion to represent the relationship b

Akimi4 [234]

$\dfrac{90}2=45$

$\dfrac{135}3=45$

$\dfrac{225}5=45$

$\dfrac{270}6=45$

The constant of proportionality is thus 45; the unit rate is 45 miles per hour.

The relationship between the time t (in hours) and the distance d (in miles) is thus $d=45\cdot t$

rodikova [14]

Answer:

a) marked-down price = $6.00

b) with-tax cost = $6.06

Step-by-step explanation:

a) The amount of the markdown is ...

0.20 × $7.50 = $1.50

so the marked-down price is ...

$7.50 - 1.50 = $6.00

b) The sales tax is ...

0.01 × $6.00 = $0.06

so the total cost with tax is ...

$6.00 + 0.06 = $6.06

_____

Of course, you know that 20% = 20/100 = 0.20, and 1% = 1/100 = 0.01.
