Ok first find out what it will cost after the 30% discount
18*.30=
$5.40 discount
$18.00-$5.40=
$12.60
Now lets figure out the sales tax
$12.60*.06=
76 cents
total price including tax is $13.36
Answer:
378.5 or just 378
Step-by-step explanation:
This is a linear model with x representing the number of generations that's gone by, y is the number of butterflies after x number of generations has gone by, and the 350 represents the number of butterflies initially (before any time has gone by. When x = 0, y = 350 so that's the y-intercept of our equation.)
The form for a linear equation is y = mx + b, where m is the rate of change and b is the y-intercept, the initial amount when x = 0.
Our rate of change is 1.5 and the initial amount of butterflies is 350, so filling in the equation we get a model of y = 1.5x + 350.
If we want y when x = 19, plug 19 in for x and solve for y:
y = 1.5(19) + 350
y = 378.5
Since we can't have .5 of a butterfly we will round down to 378
Answer:
6.4
Step-by-step explanation:
You could use a calculator
Or....
Do 345.6/54 and get 6.4
Answer:
x = $42.8
Step-by-step explanation:
Let
Amount of money shalee has in Sept = $x
Shalee October earnings = $48.24
Total money = $x + $48.24
She spent 3/4 of the money on dress
3/4 of (x + 48.24) = $68.28
3/4 * x + 48.24 = 68.28
3/4x + 144.72/4 = 68.28
3/4x + 36.18 = 68.28
3/4x = 68.28 - 36.18
3/4x = 32.10
x = 32.10 ÷ 3/4
= 32.10 × 4/3
= 128.4/3
= 42.8
x = $42.8
Answer: The answer is 4.5
