Answer:
The price of the cell phone without the coupon= $500
Step-by-step explanation:
Step 1: Express discounted amount
The discounted amount can be expressed as a function of the original cost of the phone as follows;
D=r×A
where;
D=discounted amount
r=coupon rate
A=original price of the cell phone before the coupon
In our case;
r=45%=45/100=0.45
A=a
replacing;
Discounted amount=(0.45×a)=0.45 a
Step 2: Amount she pays up
Amount she pays=Original cost of cell phone-discounted amount
where;
Amount she pays= $275
original cost of cell phone=a
discounted amount=0.45 a
replacing;
$275=a-0.45 a
0.55 a=275
a=275/0.55
a=500
The price of the cell phone without the coupon= $500
It takes 147.87 milliliter to make ice cube
<em><u>Solution:</u></em>
Given that ice cube is made of 5 fluid ounces of water
To find: milliliters of water to make to the ice cube
So we have to convert 5 ounce to milliliter
<em><u>Use the following conversion factor</u></em>
1 ounce = 29.5735 milliliter
Therefore,
5 ounce = 5 x 29.5735 milliliter
5 ounce = 147.8675 milliliter
On rounding to nearest hundred ( 2 decimal places ) , we get
5 ounce = 147.87 milliliter
Thus it takes 147.87 milliliter to make ice cube
