Answer:
W= 875+35h
Step-by-step explanation:
W= the amount of water in the pool
h= # of hours
The pool already had 875 gallons of water, so you need to add 35 times the number of hours to find the total amount of water in the pool after filling it.
The third one or last one, i’m thinking the third though
This equation looks like it is using the formula y=mx+b. You should attempt to graph it.
Answers:
Expression for the total number of quarters is 40*1.20
Amount of money you have left is 6 dollars
===================================================
Explanation:
You start with 40 quarters. 20% of this is 0.20*40 = 8 which means you found 8 more quarters. The total goes from 40 to 40+8 = 48.
A slight shortcut is to write 40*1.20 = 48
--------------
48 quarters = 48*0.25 = 12 dollars
Or you can divide by 4 to determine the total value of the quarters in dollars.
If you spent half (50%) of that money, then you'll be left with 6 dollars.
$37.95 x12= 455.4 so Kevin’s cellphone will cost 455.4 for the year
