If 10 minutes talk-time costs $2, how much will 7 minutes cost? A) $1.40
B) $1.04
C) $1.34

A

Step-by-step explanation:

10=2

7=Xthen

10x=14,we divided both side by 10and we get

1.4$

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
