a bridge currenly has 975 vehicles traveling on it per hour during peak time. a traffic engineer estimates that there will be 3.4%more vehicles traveling on the bridge for two years. How many more cars will travel on the bridge per hours during peak time in 2 years than are traveling now? Round your final answer to the nearest whole vehicle.
Accepted Solution
A:
To determine how many more cars will travel on the bridge during peak time in two years, you will find what 3.4% of 975 vehicles is for the first year.
Add this number to the 975, and then multiply 0.034 times the new number of vehicles.
Here is the math:
0.034 x 975 = 33.15
This round to 33 more vehicles. 975 + 33 = 1008
0.034 x 1008 = 34.272
There will be about 33 + 34 (67) more vehicles on the bridge in two years.
