Jessica has an account with a credit union. Her account earns 2.5% simple interest yearly. Exactly a year and a half ago, she opened her account with $900.

The interest earned by Jessica after a year and a half of investment is $ 33.75.

Step-by-step explanation:

First, we must establish that simple interest is one in which interests are not added to capital. Therefore, interest in this case will always be calculated on the initial basis of $ 900.

That said, if Jessica invested $ 900 in her account, and said account grants a simple annual interest of % 2.5 per year, that account grants an interest of $ 22.5 per year (since 900 x 2.5 / 100 = 22.5). Therefore, to know the interest obtained in a year and a half, we must perform the following calculation:

22.5 (annual interest) + 22.5 / 2 (half-year interest) = X

22.5 + (22.5 / 2) = X = 33.75

Therefore, the interest obtained by Jessica after a year and a half of investment is $ 33.75.

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.
