Hello from MrBillDoesMath!
Answer:
If n is even, sum = n/2.
If n is odd, sum = (n-1)/2 - 16

See attached doc and ask questions!
Thank you,

You have
3/12 = x/16
Multiply by 16
16*(3/12) = x = 4
x = 4
Answer:
B) 181
Step-by-step explanation:
3*5=15
45*4=180
24/2=12
12-4=8
5*2=10
15+190-12+10-10=181
<em><u>4 pints of strawberries and 2 pints of blueberries are bought</u></em>
<em><u>Solution:</u></em>
Let "a" be the pints of strawberries bought
Let "b" be the pints of blueberries cost
Cost per pint of strawberry = $ 1.60
Cost per pint of blueberry = $ 2.30
<em><u>A shopper bought twice as many pints of strawberries as pints of blueberries</u></em>
Therefore,
a = 2b --------- eqn 1
<em><u>They spent a total of $11.00. Therefore we frame a equation as:</u></em>
pints of strawberries bought x Cost per pint of strawberry + pints of blueberries cost x Cost per pint of blueberry = 11

1.6a + 2.3b = 11 --------- eqn 2
<em><u>Substitute eqn 1 in eqn 2</u></em>
1.6(2b) + 2.3b = 11
3.2b + 2.3b = 11
5.5b = 11
Divide both sides by 11
b = 2
<em><u>Substitute b = 2 in eqn 1</u></em>
a = 2(2)
a = 4
Thus 4 pints of strawberries and 2 pints of blueberries are bought
write an equation for the purchase :
$12 + 2x + tax = $30.45
(12 +2x)* 1.05 = 30.45
solve for x to get
x = $8.5
the price of a pair of regular socks is $8.50
