The function 56 – 4y = –5x can be used to determine the total amount of money in a coin jar, y, after money isadded for x days. What is the rate of change in dollars with respect to the number of days?

$1.25 dollars per day added to the coin jar

Step-by-step explanation:

the given equation is: 56 – 4y = –5x

we can rewrite it:

4y = 56 + 5x

y = (56 + 5x) / 4

y = 14 + ⁵/₄x

the slope of the equation is ⁵/₄, which gives us how much money is added into the coin jar every day. We can write ⁵/₄ as 1.25 or $1.25 dollars per day added to the coin jar
