Kaya's family spends $105 to rent a boat for 7 days. The total cost, c, of the boat rental is proportional to the number of days
Elza [17]

Answer:

c=15d

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form k=\frac{y}{x} or y=kx

Let

c ----> the total cost of the boat rental

d ---> is the number of days, the family rents the boat

we know that

Kaya's family spends $105 to rent a boat for 7 days

so

For d=7 days, c=$105

Find the value of the constant of proportionality k

k=\frac{c}{d}

substitute the given values

k=\frac{105}{7}=\$15\ per\ day

therefore

The linear direct equation is equal to

c=15d

Monica has $20. She needs to buy a gallon of milk that costs $2.50. She also wants to buy yogurt, which costs $1.20 a cup. What
trapecia [35]

Answer: The greatest number of cups of yogurt MOnica can buy is 14.

Step-by-step explanation:

If she  need to buy a gallon of milk then it means that $2.50  will be deducted from the money .  

Use the the inequality to solve for how many cups of yogurt Monica can buy

1.20x + 2.50 ≤ 20

             -2.50   2.50

1.20x ≤ 17.5

x≤14.5833...  

which means the greatest number of  cups of yogurt Monica can buy is 14.

Your typical markup for merchandise is 40%. your cost on an item is $8.00. calculate the selling price.
adoni [48]
The selling price would be $11.20.

40% = 40/100 = 0.4

The mark up is 40% of the cost; this means 40% of 8:

40% of 8 = 0.4(8) = 3.20
8 + 3.20 = 11.20
