In this situation, which equation is NOT equivalent to the rest? Mrs. Jones deducts $3 from each of her 5 children's allowances
lawyer [7]

Answer:

c. 5x - 3 = 125

Step-by-step explanation:

Mrs. Jones deducts $3 from each of her 5 children's allowances this week because they didn't finish their chores. They then received a total of $125 in allowance. a. 5(x - 3) = 125

b. 5x - 15 = 125

c. 5x - 3 = 125

d. 5x = 140

Solution:

Let x represent the allowance for each of Mrs. Jones children. Since she deducts $3 from each children because they didn't finish their chores, the allowance for each child becomes x - 3.

There are 5 children, hence the allowance for the 5 children would be:

5(x-3)

Since they received a total of $125 in allowance, hence:

5(x-3) = 125

5x - 15 = 125

5x = 125 + 15

5x = 140

Option c is wrong
