He mitchell family is renting a boat for the day. the boat rental has a flat fee of $100 plus $20 for each hour. they have to pay for a whole hour even if they are not out on the lake for a whole hour. for example, if they rent the boat for 3 and one-half hours, they have to pay for 4 hours. if they want to spend $250 or less on the boat rental for the day, how many hours can they rent the boat? write an inequality and solve.

They can rent the boat for 7 hours for $ 240 in total.

Since the Mitchell family is renting a boat for the day, and the boat rental has a flat fee of $ 100 plus $ 20 for each hour, and they have to pay for a whole hour even if they are not out on the lake for a whole hour, to determine, if they want to spend $ 250 or less on the boat rental for the day, how many hours can they rent the boat, the following calculation must be performed:

So they can rent the boat for 7 hours for $ 240 in total.

250-100 = 150

150/20 = 7.5

7 hours

inequality: 100+20x <=250

because its not ur topic and its not for is for homework not that.

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.
