Answer:
Rational
Step-by-step explanation:
Rational numbers can be reduced to a fraction
Irrational numbers cannot be reduced to a fraction
Whole numbers are positive numbers that are not decimal or fraction
Integers are all numbers that are not decimal or fraction
Assuming yo meant
f(x)=(1/3)4x²
sub 4 for x
f(4)=(1/3)4(4)²
f(4)=(1/3)4(16)
f(4)=(1/3)64
f(4)=64/3
I’m assuming the question is what is the price of one mug WITHOUT the sale.
So since the price of 5 mugs is $28.20, we can work out the price of one mug with the sale.
We do this by doing:
$28.20 / 5
Which gives us:
$5.64 per mug during the sale.
To work out the price of a mug without the sale, we simply add on the amount that has been taken off (which we know is $1.75 because the question says so):
$5.64 + $1.75 = $7.39
Therefore we can conclude the price of a mug without a sale is $7.39
And the price of a mug during the sale is $5.64.
I hope this helps!
