Michaela transferred a balance of $5275 to a new credit card at the beginning of the year. The card offered an introductory APR of 8.1% for the first 4
months and a standard APR of 34.5% thereafter. If the card compounds
interest monthly, which of these expressions represents Michaela's balance
at the end of the year? (Assume that Michaela will make no payments or new
purchases during the year, and ignore any possible late payment fees.)

35-60 students are taking math.

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
