Step-by-step explanation:
Given the fabric store sells the fabric for $6.97 per yard
Given that a customer buys 7/8 yard of fabric.
Let the cost the customer pays be x then
on cross multiplication we get
x=6.01
Therefore the amount the customer should pay is $6.01

Answer:
5 miles
Step-by-step explanation:
It may get a bit messy, but we can solve for the desired value directly. Let d = the distance walked (in miles). Then 20-d is the distance traveled in the car. The relevant relation is ...
time = distance / speed
The total travel time is 9:00 -6:50 = 2:10 = 2 1/6 hours = 13/6 hours. Here is the equation for total travel time.
total time = time spent walking + time spent riding
13/6 = (d/3) + (20-d)/30
Multiplying by 30 gives ...
65 = 10d + 20 -d
45 = 9d . . . . . . . . . . subtract 20
5 = d . . . . . . . . . . . . divide by 9
The girl walked 5 miles.
_____
<em>Check</em>
Her walking time was (5 mi)/(3 mph) = 5/3 h = 1:40.
Her riding time was (15 mi)/(30 mph) = 1/2 h = 0:30.
Her total travel time was 1:40 +0:30 = 1:70 = 2:10, as required.
Answer:
1. 70%
2. Yes
Step-by-step explanation:
1. there are 7 that are over 48, and 10 total. so, 7/10, or 70% would be our answer.
2. 70% is greater than 65%, so yes. he did it better than them.
