Answer:

k = 4

Step-by-step explanation:

if direct variation exists,

input * k = output

here, number of baskets = input and cost = output

3 * k = 12

5 * k = 20

6 * k = 24

8 * k = 32

15 * k = 60

does this always work for one k?

let's try it out

3 * k = 12

divide both sides by 3 to solve for k

k = 4

5 * k = 20

divide both sides by 5 to solve for k

k = 4

6 * k = 24

divide both sides by 6 to solve for k

k = 4

8 * k = 32

divide both sides by 8 to solve for k

k = 4

15 * k = 60

divide both sides by 15 to solve for k

k = 4

as k = 4 no matter what, there is a direct variation with k = 4

natta225 [31]
Hi there:-)

Unpaid balance=60.15−51=9.15
Finance charge=9.15×(0.18÷12)=0.14
New balance=9.15+0.14+91.27=100.56

Hope it helps
