Answer:
Infinitely many
Step-by-step explanation:
The second equation is basically multiplying the first equation by 2, so this means that they will have the same rate of change and initial value. Therefore, there are infinitely many solutions.
Write an equation based on the problem
3.25 is fixed cost, and 1.80 is variable cost, so the equation will be
3.25 + 1.80x = 19.00
x represents the distance she can travel
Solve the equation
3.25 + 1.80x = 19.00
1.80x = 19.00 - 3.25
1.80x = 15.75
x = 15.75/1.80
x = 8.75
She can travel 8.75 miles for the taxi ride
The actual distance is 280 miles
The distance for round trip is 560 miles
It costs $ 72.8 for gas on a round trip
<em><u>Solution:</u></em>
Given that,
Sean is looking at an atlas and the key at the bottom shows for every 1 and 1/2 inch on the map is approximately 80 miles of actual distance
Therefore,
Sean measured it to be about 5 and 1/4 inches on the map
Let "x" be the actual distance
Thus, we can say,
This forms a proportion and we can solve the sum by cross multiplying
Thus the actual distance is 280 miles
<em><u>How far will Sean drive round trip (there and back, no sightseeing)? </u></em>
Round trip = 280 + 280 = 560 miles
If Sean’s car gets 20 miles per gallon and gas averages about $2.60 a gallon, approximately how much will Sean spend on gas for a round trip?
cost = 28 x 2.60 = 72.8
Thus it costs $ 72.8 for gas on a round trip
