The ratio table below shows the relationship between the weight of apples purchased and the total cost of the apples. Apple Cost
Weight (lb)
Total cost ($)
1
2

10
20

When the weight of apples is increased by a factor of 4, by what factor does the total cost increase

sure i'm up for it

step-by-step explanation:

a and c

for infinitely many solutions we require both left and right sides to be equal

distribute and simplify

a

14 - 8x = 20 - 8x - 6 = 14 - 8x ← both sides equal so infinite solutions

b

6x - 54 = 6x - 54 + x = 7x - 54 ← not equal

c

4x + 16 = 4x + 10 + 6 = 4x + 16 ← both sides equal so infinite solutions

d

5x - 40 + 10 = 5x + 10

5x - 30 = 5x + 10 ← not equal

good luck on ur quiz test or homework. have a good day : )
