### Ghelo's Percent Scribe Post

Textbook Page 148 -149
Questions : 4,5,6

4. Chris purchased the following items:
• 2 binders at \$4.99 each
• 1 math set for \$3.99
• a backpack for \$19.99
Find the total cost including 5% GST
and 7% PST
(\$4.99 each)
2 binders = \$10
1 math set = \$4 (\$3.99)
a backpack =+\$20 (\$19.99)
--------------------------------
With tax ( 12% or 1.12) it will equal \$38. 08 because I put on my calculator \$34 x 1.12 and I got \$38.08

\$38.08 is now the total price

5.Ravi purchased 3 DVDs for \$19.99 each.
Find the total cost for the DVDs including
5% GST and 6% PST.

1 DVD = \$20
1 DVD = \$20
1 DVD = +\$20
-----------------------
3 DVDs = \$60

With tax ( 11% or 1.11) it will equal \$66.6 because I put on my calculator \$60 x 1.11 and I got \$66.6

\$66.60 is now the total price

6. A store discounted items by 50% off the
original price one week. The following
week an additional 10% was taken off the
already reduced price. The regular price
of a CD player was \$85.00. What is the
reduced price in the second week?

CD player = \$85 ( 50%)
\$85 x 0.5 (because 0.5 is 50%) and I got \$42. 50 (10%)
Since we know that 42.50 is half we can Multiply 42.50 x 0.1 to get \$4.25
So now we take 42.50 - 4.25 = \$38.25
\$38.25 is now the sale price
