Amount of tip she gave,
Amount of tax given :
So, total amount she paid is :
Total = Actual cost + Tip + Tax
Total = $(15 + 3 + 1.35 )
Total = $19.35 .
Therefore, total amount she paid is $19.35 .
Hence, this is the required solution.
Answer:
Step-by-step explanation:
Case I: use common logs:
2x log 3 = log 4, or 2x(0.47712) = 0.60206
Solving for x, we get 0.95424x = 0.60206, and then x = 0.60206/0.95424.
x is then x = 0.631
Case II: use logs to the base 3:
2x (log to the base 3 of 3) = (log to the base 3 of 4)
This simplifies to 2x(1) = 2x = (log 4)/log 3 = 1.262. Finally, we divide this
result by 2, obtaining x = 0.631
Answer:
y - 7 = -2(x - 4)
Step-by-step explanation:
We are asked to write the equation of a line in point slope form
Step 1 : find slope
We are given the slope to be -2
Slope m = -2
Step 2: substitute m into point slope form
y - y_1 = m( x - x_1)
y - y_1 = -2 ( x - x _1)
Step 3: substitute the point into the equation
y - y_1 = -2( x - x _1)
( 4 , 7)
x_1 = 4
y_1 = 7
y - 7 = -2( x - 4)
We don't need to open the bracket because we are asked to write the equation in a point slope form
