Sarah is 6 years older than Amy.
Umnica [9.8K]

Answer:

B.

Step-by-step explanation:

The problem has got to be addition.

The sentence "Sarah is 6 years older than Amy." does not include any hint of subtracting, or multiplying.

A hint of multiplying in a expression would be the word 'times', like "Brandon is 6 times the age of Emily" which eliminates D.

A hint of subtraction in an expression would be the word 'less', like "Brandon is 6 less the age of Emily." which eliminates A and C.

The word 'older' indicates addition, or adding, and if it would have been subtraction, the keyword would be 'younger' because you are subtracting their age, like 19 - 11. The same goes with B, but adding.

Finally, we now know that it is B because there is no other addition choice.

I hope this helped. Please correct me if I am wrong.

Thepotemich [5.8K]
1) subtract 42.5 miles from 68 miles to find the gross change in distance:  It is 25.5.  Since this is a decrease, write -25.5 miles.
2) divide -25.5 miles by the original distance, 68 miles:
     -0.375
3) multiply this by 100% to find the percentage decrease:
     -37.5% (answer)
