Answer:
Step-by-step explanation:
The first choice is correct
The rate is 20 per dog, thus we get the equation:
c= 20d
However the first dog is free, so the equation becomes
c = 20(d - 1)
And he also has a walking fee of 85 dollars and thus the equation becomes
c= 85 + 20(d-1)
Answer:
21
Step-by-step explanation:
The answer is 21, because we use the combinations formula
7!/(7-2!)(2!) = 6x7/2 = 21
The total amount she spent is equal to the sum of the amount for food and hotel accommodation. Letting x be the percent tax that Tracy was charged for his food, the equation that best represent the given is,
280.74 / 3 = 49 + (0.10)(49) + 32 + (0.15)(32) + (x)(32)
The value of x from the equation is 0.09. Thus, Tracy is charged 9% tax on his food.
Answer: You are correct.
Step-by-step explanation: You are correct because 126 divided by 6 equals 21.
$6*127 + $3 * (number adults) = $1053
3a = 291
a = 97
c = 127-97 = 30
