Answer:
x = 175 km
Step-by-step explanation:
We can use ratios to solve this problem. Put the map distance over the real life distance.
1 cm 7 cm
-------- = ---------
25 km x km
Using cross products.
1 * x = 7 * 25
x = 175 km
Step-by-step explanation:
letπ be the percentage of her savings
=40+85
=125
=125+π=100
=π=100-125
=π=75
