Bella and Heather put some money in their money boxes every week. The amount of money (y) in dollars, in their money boxes after
evablogger [386]

The question is incomplete:

Bella and Heather put some money into their money boxes every week. The amount of money (y), in dollars, in their money boxes after a certain amount of time (x), in weeks, is shown by the equations below: Bella: y = 25x + 60 Heather: y = 30x + 10 After how many weeks will Bella and Heather have the same amount of money in their money boxes, and what is that amount?

 10 weeks, $10  

10 weeks, $310  

9 weeks, $310  

310 weeks, $10

Answer:

10 weeks, $310  

Step-by-step explanation:

As the statement indicates, you have the following equations:

y=25x+60

y=30x+10

where:

y= the amount of money

x= the amount of time in weeks

You can equalize the expressions and isolate x to find the number of weeks after which Bella and Heather will have the same amount of money:

25x+60=30x+10

60-10=30x-25x

50=5x

x=50/5= 10

After this, you can replace the value of x in any of the equations to find the amount of money that they will have after 10 weeks:

-y=25(10)+60=310

-y=30(10)+10= 310

According to this, the answer is 10 weeks, $310.

In-s [12.5K]

3.03 days

Step-by-step explanation:

We first look up the Z-score for 90th percentile in the table;

= 1.282

Z score is given by the formula;

X – μ / σ

We are given μ as 5.2 while σ is 2.2. Therefore;

1.282 = X -  5.2 / 2.2

1.282 * 2.2 / 5.2 = X

3.03018 = X

= 3.03
