Answer:
$15
Step-by-step explanation:
Let d represent the cost of the dinner before tip. Then $15 = 0.20d, since 0.20 is the decimal fraction corresponding to 20%.
Solving for d, the cost of the dinner, we divide both sides of the equation $15 = 0.20d by .20, obtaining:
$15
d = ------------ = $75
0.20
The cost of the dinner before tip was $75.

80 × 4
320 cm³
Its actually a mixed number that is 1 1/20 since you can reduce it from 1 5/100
The equation in terms of x, for the total time he takes in hours would be 2.48 = 12/x + 26/10x
<h3>What is speed?</h3>
Speed can be calculated as the ratio of distance traveled to the time taken
Darpan runs a distance of 12 km and then cycles a distance of 26 km.
Total distance = 12 + 26 = 38km
The running speed is x km/h
A = x
The cycling speed is 10 km/h faster than his running speed
B = 10x
He takes a total time of 2 hours and 48 minutes.
So, the total time he takes
Time = Distance x speed
2.48 = 12/x + 26/10x
10x(2.48) = 120 + 26
24.8x = 146
x = 5.8
