A music store is selling posters and CDs. Each poster gives a profit of $4.00 and each CD gives a profit of 6.25 The store needs to make an average profit of $300 per hour to stay in business. Let x represent the number of posters
sold and y represent the number of CDs sold. Write and graph an inequality showing how many of each item (posters
and CDs) the store needs to sell per hour to make a sufficient profit.

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150

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.

i believe that the answer is y+6=1/3(x+2)
