Answer:

150 - 7.50x = 112.50

x = 5

Step-by-step explanation:

Spent in x days: 7.50x

Initial - spent = remaining

150 - 7.50x = 112.50

If x is also to be found:

150-112.5 = 7.5x

37.5 = 7.5x

x = 37.5/7.5

x = 5

Answer:

5 Days

Step-by-step explanation:

<u>Step 1: Make an expression</u>

150 - 7.50x = 112.50

<u>Step 2: Solve the expression for x</u>

150 - 7.50x = 112.50

150 - 7.50x - 150 = 112.50 - 150

-7.50x / -7.5 = -37.5 / -7.5

x = 5

Eddi Din [679]

Answer:

15 students

Step-by-step explanation:

The fraction of students who will repeat the exam is:
