<h3>Specific Gravity</h3>

Specific gravity of a substance is defined as the relative density of substance. This can be further said to be the ratio between the density of a substance to the density of the reference substance.

mathematically;

relative density = \frac{density of substance}{density of reference}

The value 0.92 indicates the relative density of the ice.

Miguel decided to buy a cell phone for $150. It is currently on sale for 10% off. When he got to the counter, he got an addition
aleksandrvk [35]

Answer:

The final cost price of the cellphone is  $121.5

Step-by-step explanation:

The marked price of the cell phone = $150

Now, sale percentage on the marked price = 10%

Now, 10 % of 150 = \frac{10}{100}  \times 150 = 15

⇒The sale discount on the marked price = $15

So, the  selling price of cellphone = Marked Price - Sale discount

                                                        = $150  - $15  = $135

Now, the second discount offered on $135 is 10%

10 % of 130 = \frac{10}{100}  \times 130 = 13.5

⇒The additional sale discount on the selling price = $13.5

So, the final cost of cellphone = Selling Price - Additional Sale discount

                                                        = $135  - $13.5  = $121.5

Hence, the final cost price of the cellphone is  $121.5
