Step-by-step explanation:
Given data
Cost of bike= £250
<em>Assuming she works for 6 days</em>
1.Babysitting
6*2.75=£16.5 per day
for 6 days
=16.5*6
=£99
2. Saturday Job
=£27.50
Total earnings for the week
=£27.50+£99
=£126.5 weekly
Hence it will take her
=250/126.5
=1.97 week
Approximately 2 weeks to save up the amount
Since the exponent of the scientific notation is negative (-3), move the decimal point 3 places to the left. 0.005.
Let's note the information.
This is what we know:
Every buttons came in packages of 30 per student.
Every bookmark came in packages of 50 per person.
Know, we need to do some multiplying.
30 x 400 & 50 x 400
Now solve.
30 X 400 = 12000.
So we now know that they have an estimated 12000 buttons total.
Now, we find x for bookmarks.
50 x 400 = 20000
That means total that estimated that 20000 bookmarks will be given.
The two equations are scale factors, to find the missing number, divide the equations by each other.
36 ÷ 4 = 9.
The scale factor is 9, so multiply 5 by 9 to find b.
5 × 9 = 45.
B = 45.
I hope that helps!
