Write an equation that models this problem: Trevor paid$528 to stay at the MGM Grand Hotel in Las Vegas for four nights over New Year's weekend. What was the rate, r, per day to stay at the MGM Grand for New Year's?

r = $105.6

Step-by-step explanation:

Given,

Amount paid by Trevor for 4 nights = $528

Rate per day = r

Now,

We know that a 4-night stay in the hotel means 5 days to stay at MGM Grand.

Now,

Amount paid = Number of days x Rate per day

$528 = 5 r

r = $105.6

Hence, Trevor pays $105.6 to stay at the MGM Grand Hotel in Las Vegas for four nights.

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
