HELPP with this please

Example 2: A rental home on Airbnb rents for $100 a night for the first three nights, $90 a night for the next three nights, and $80 a night for each remaining night. The total cost is a function of the number of nights that a guest stay. Write the piecewise-defined function .

What is the cost of staying 5 nights? 10 nights

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x

answer by jkismyhusbandbae:

a) how close a measured value is to the actual (true) value.

  measure of length.   there are 12 inches in a foot, and 36 inches in a yard.   one inch is exactly 2.54 centimeters.

accuracy is how close something is to an actual answer but it is not exactly correct.
