Answer:

4% Hope this helped.

Step-by-step explanation:

The formula is: final value minus starting value divided by the starting value then times 100

THIS FORMULA ONLY APPLIES TO PERCENT INCREASE

<u>Final Value−Starting Value</u>

Starting Value x100

Plug numbers in

2600-2500/2500 x 100

100/2500=0.04

0.04x100

=4%

First we set up an “x”, cuz we don’t know the exact percentage and x will help us to find it.
Then, we know the salary increased so there must be 1+the percentage.
Next, we only have to figure this equation out.
Notice you final answer should be the percentage so we change the decimal to percentage.

Your beginning balance on your lunch account is $42. You buy lunch for $1.80 every day and sometimes buy a snack for $0.85. Afte

tangare [24]

Answer:

The answer to your question is: I bought 7 snacks

Step-by-step explanation:

Data

beginning balance = $42 = b

lunch = $1.80 = l

snack = $ 0.85 = s

final balance = $0.05 = f

f = b - 1.8l - 0.05s

0.05 = 42 - 1.8l - 0.85s

After 20 days I spent = 1.8(20) in lunches = $36

0.05 = 42 - 36 - 0.85s

0.05 = 6 - 0.85s

0.05 - 6 = -0.85s

-5.95 = -0.85s

s = -5.95/-0.85

s = 7

This month Erica saved $20 more than last month. For the two months, she saved a total of $70. How much did she save each month

If its 20 more than last month that means x + $20 = $70, solve that and you get x = $50, last month she saved $50

Answer:

Step-by-step explanation:

To do this there are many steps

Step 1: Turn the whole bathroom into a regular rectangle, so a 7.5x9.5 size bathroom or 71.25 sq ft.

Step 2: Figure out the area of the missing spaces

To do this you need to figure out the side lengths, so for the right tall side, its 7.5 and for the left its 6.5, there is a 4 and a 3, you take that and you can figure out the first spot in pink is .5x4=0.20 then the second one, you find the side length difference and thats the height (1) and then you know the width is 5 so 5x1=5 add those, 5+0.20= 5.20 and subtract that value from 71.25 to get her actual value, 66.05

I hope this helps, when i was writing the steps i decided it would be easier to write on the shape, so i am attaching that, I hope i helped you (:
