Question

Kendra hasn’t missed a day of school in 245 days. This is twenty days less than five times the number of days it has been since Brandon has missed a day of school. How many days has it been since Brandon missed a day of school?

Answer 1

The answer is 53

245 = 5y - 20 | y = 53

Explanation:

subtracting 20 ( - 20) represents "twenty days less"

5y represents "five times the number of days"

This is all being compared to Kendra's 245 days of perfect attendance which is why it's "245 ="

Plug it in! & don't forget PEMDAS ----> 5(53) - 20 = 245

Answer 2

The equation would be 5x+20=245
X=the number of days Brandon missed.
Subtract 20 from both sides; 5x=225
Then divide by 5; x=45
It has been 45 days since Brandon missed school.
