david has 25 dallars in his savings account and is saving up money to but a new bike. he starts to put back 5 dollars per week into his savings. write an equation to represent this

The equation that represents this situation is y = 5x + 25

Step-by-step explanation:

The form of the linear equation is y = m x + b, where

∵ David has 25 dollars in his savings account

→ That means 25 is the initial amount

∴ b = 25

∵ He starts to put back 5 dollars per week into his savings

→ That means the rate is 5 dollars per week

∴ m = 5

→ Assume that his total saving after x weeks is y dollars

∵ y is his total saving in x weeks

→ Substitute the values of m and b in the form of the equation above

∴ y = 5x + 25

∴ The equation that represents this situation is y = 5x + 25
