Janet has $120.if she saves $20 per week,in how many days will she have $500

malfutka [58]

It will take 133 days for Janet to save the money.

In order to find this, start by finding out how much more she needs to save. To find this, subtract the amount she has from the total goal amount.

500-120 = 380

So we know that she needs $380. To find how many weeks that it, divide the total amount needed to save by the amount she can save a week.

380/20 = 19 weeks.

Now to find the number of days, multiply the weeks by the number of days in a week.

19 x 7 = 133 days

Question 1 (1 point)

insens350 [35]

Answer:

1. q = p - mn

2. c = -6

3. 10

Step-by-step explanation:

$mn=p-q\\\textsf{add q to both sides}\implies mn + q = p\\\textsf{subtract mn from both sides}\implies q = p-mn$

$5c+23=c-1\\\textsf{subtract 23 from both sides}\implies5c=c-24\\\textsf{subtract c from both sides}\implies4c=-24\\\textsf{divide both sides by 4}\implies c=-6$

$4f^2-g\\\implies 4(2)^2-3=13\\\\3f^2-3g\\\implies 3(2)^2-(3 \times3)=3\\\\13-3=10$

At one point in a Girl Scout cookie sales drive, region C had sold 1500 boxes of cookies, and region D had sold 1200 boxes of co

juin [17]

Answer:

a)After 6 days region D will catch region C

b) Region C will sell 13500 cookies and region D will sell 13600 cookies

Step-by-step explanation:

a) Cookies sold by region C more than region D= 1500-1200=300

But region D can sells 50 cookies every day i-e

50 cookies = 1 day

==> 1 cookie= 1÷50

==> 300cookies = 300÷50=6 days

So, after 6 days region D will catch up region C's

b) If sale stopped after 8 days;

Then sale of region C for 8 days = 1500×8=12000 cookies

so , total cookies sold = 1500 +12000=13500

For region D;

Before catching up region C cookies sold by region D = 1200

Till catching up region C - region D had also sold 1500 cookies,

and for 50 extra cookies than region C

next 8 days region D will sale =(1500+50)×8=1550×8=12400 cookies

So, total number of cookies sold by region D = 1200+12400=13600
