Answer:
43% of the trip
Step-by-step explanation:
1. Create an Equation
300 miles/100*x percent=129 miles <=== Make an equation so you can find the percent she slept of the trip
2. Solve
300 miles/100*x percent=129 miles
3x=129 <=== 300 divided by 100 is 3 and 3 times x is also 3x
3x/3=129/3 <=== divide by 3 from both sides
x=43
Since x is 43 that means 129 equals 43% which is how much Tallulah slept
of the trip.
3. Check
300 miles/100*43%=129 miles <=== Substitute x with 43%
3x43%=129
129=129 <=== 129 is 129 which means that the answer is correct!
