Answer:
20 + 5m = 140
$24 on each day of the last five days
Step-by-step explanation:
Total amount to spend in 6 days = $140
He spent:
First day = $20
Balance = Total amount to spend - Amount spent on first day
= $140 - $20
= $120
He spent the same amount of money during the next five days.
Amount spent each day in the last 5 days = Balance / 5 days
= 120 / 5
= 24
Amount spent each day in the last 5 days = $24
The equation is
20 + 5m = 140
Where,
m = amount spent in the last five days
20 + 5m = 140
5m = 140 - 20
5m = 120
m = 120 / 5
m = $24

<h3>What is an equation?</h3>
A mathematical equation is the representation of a problem by the use of variables. Often times, an equation is formed from the factors that are in a problem.
We have to represented each of the books read with an algebraic term;
Let the number of mystery books be y
Let the number of sports books be x
Total number of books = 23
We know that;
x + y = 23
but y = 10
x = 23 - 10
x = 13 books
