Question

Sara's savings account balance changed by -$34 one week and by -$67 the next week .Which amount represents the greater change?

Answer 1

Answer:

Change in one week is more than the change in the next week

Step-by-step explanation:

Change in Sara's savings account balance in one week = $- \ 34$

Change in Sara's savings account balance in next week = $- \ 67$

Tens digit in 34 = 3

Tens digit in 67 = 6

If we compare the tens digit of 34 and 67, we get $6> 3$

So, $67> 34$

On multiplying both sides by -1 , we get $-67< -34$.

{ We know that negative sign changes sign of inequality }

So, we get change in one week is more than the change in the next week .

Answer 2

The greater change is represented by the absolute magnitude

|-34| = 34
|-67| = 67

67 > 34

-67 represents the greater change
