Alex raised $138.75 for his school's Walk-A-Thon. He donated $14.50 of his own money and wrote the equation d - 14.50 = 138.75 to find out how much was donated by others. Determine his mistake and correct it.

Sagot :

Answer:

The minus shouls be a plus.

Step-by-step explanation:

138.75 is the total that everyone donated, Alex himself and others. Thus, 138.75 = d + 14.50.

How Alex wrote it implies that 14.50 was taken away from the donations of others to get the total of 138.75
