You have $60 and your sister has $120. You are saving $14 per week and your sister is saving $10 per week. How long will it be before you and your sister have the same amount of money? What amount would you have the same?
Please use an equation to solve the problem.

The time when you will have the same amount with your sister is 15 weeks

The amount you will have the same is $270

The given parameters;

Let the time when you will have the same amount with your sister = x

The number of weeks in which you will have the same amount is calculated as;

The first equation will be;

60 + 14x

The second equation will be;

120 + 10x

Set the two equations to be equal to each other;

60 + 14x = 120 + 10x

14x - 10x = 120 - 60

4x = 60

The amount you will have the same is calculated as;

= 60 + 14(15)

= 60 + 210

= $270

x=15 weeks

amount= 60+14*15= $270

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
