Answer:
Step-by-step explanation:
3 coins pulled are 10 cents or more
5 coins are under 10 cents
so 3 out of 8 coins are 10 cents or more
the jar contains 200 coins
This is a ratio problem 3 is to 8 as x (an unknown value) is to 200
3/8 = x/200 solve for x
times both sides by 200
200(3/8) = x solve directly here using a calculator
600/8 = x or keep similifying until you can divide more
300/4 = x easily I kept dividing the numerator and the
150/2 = x denominator by 2 until i got 150/2 = 75
75 = x

$37.50
-------------------------------------------------------------------------------
Discount
-------------------------------------------------------------------------------
8% of $37.50
= 0.08 x 37.50
= $3
-------------------------------------------------------------------------------
Price after Discount
-------------------------------------------------------------------------------
$37.50 - $3 = $34.50

8% 0f $34.50
= 0.08 x 34.50
= $2.76
-------------------------------------------------------------------------------
Price with Sales Tax
-------------------------------------------------------------------------------
$34.50 + $2.76 = $37.36
