How many coins did julia collect
kondor19780726 [428]

Answer:

The number of coins Julia found is 5

Step-by-step explanation:

We know that the total number of gold coins collected divided by the number of people collecting is 6. So we can set up an equation:

\frac{6+5+6+8+x}{5}=6

this simplifies to:

\frac{25+x}{5}=6

Using the multiplication property of equality and multiplying both sides by we get:

25+x=30

Then finally, using the subtraction property of equality we get our answer:

x=5

marysya [2.9K]

Answer:

If the television is on sale for 15%, that means that the selling price before tax will be 100 - 15 = 5% of the original price.

1250 * 0.85 = $1062.5 ... this is your selling price BEFORE tax

Now, calculate your tax.

You would pay (1062.5) + (1062.5 * 0.065)  

= 1062.5 + 69.06 (your tax)

= 1131.56 dollars
