1 product = $65.00
20 products = 65 x 20 = $1300
Sales Tax = 3.5% of $1300 = 0.035 x $1300 = $45.50
Total = $1300 + $45.50 = $1345.50

Answer: $1345.50

Answer:
-x + y = 0 or x - y = 0
Step-by-step explanation:
The line passes through points (0, 0) and (4,4), then its slope is:
m = (4 - 0)/(4 - 0) = 1
Given that the line passes through (0, 0), its y-intercept is
b = 0
Using slope and y-intercept form:
y = mx + b
y = x
The standard form of a line is:
Ax + By = C
So, we have to put all variables on the left side, as follows:
-x + y = 0
Multiplying by (-1) at both sides:
x - y = 0
Answer:the mass of the air inside the inflated balloon is 4 grams
Step-by-step explanation:
The initial mass of the balloon before it was inflated by the Math and Science class is 4 grams. After the balloon was inflated, the mass was 8 grams. This means that the mass by which the balloon increased would be the mass of the inflated balloon - the initial mass of the balloon. It becomes
8 - 4 = 4 grams.
Therefore, the mass of the air inside the inflated balloon is 4 grams.
