Answer:
200 hats
cost = 65.16
Step-by-step explanation:
There are 60 baseball caps and 30% of all hats are baseball caps
baseball caps = hats times percentage baseball caps
60 = hats * 30%
60 = hats *.30
Divide each side by .30
60/.30 = hats *.30/30
200 = hats
There are 200 hats in the store
We want to buy 2 blue baseball hats at 30 each at 8.6% sales tax
The cost of the hats is
2*30 = 60
Now we need to find the tax
tax = cost * sales tax rate
tax = 60 * 8.6%
tax = 60 *.086
tax = 5.16
The total cost is the cost of the hats plus the tax
total cost = cost + tax
=60+5.16
=65.16
for all of these, you just have to divide by -1 to make the variable positive however you have flip the inequality sign when you divide by a negative number.
c > 1
-2 > v
y > 1
z > 6
1 > w
10.5 to 8.75 not sure if you want a simpler answer....
or a whole number answer..... 42 to 35
We will be using PEMDAS rule here :
P
- Parentheses first
E
- Exponents (ie Powers and Square Roots, etc.)
MD
- Multiplication and Division (left-to-right)
AS
- Addition and Subtraction (left-to-right)
8+2(12-5)
Step 1:
Solving parenthesis first:
8+2(7)
Step 2:
Multiplying 2*7
8+14
Step 3:
Adding 8 and 14
