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, d, the family rents the boat. How much does it cost, in dollars, to rent the boat for one day?

Im sure its Answer A: $15 (Because $105 divided by 7 = $15)  Or, Answer B: C = 15d (Because the cost will equal 15 dollars a day)

$15/day

Step-by-step explanation:

If the rent is proportional to the number of days, the dividing the total cost by the number of days will tell you the price of each day:

105/7=15

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9
