Use mental math to approximate what a 15% tip would be for a bill of $31.99.
rodikova [14]

The whole bill is $31.99 that is 100%. You can use mental math to determine exatcly 15% from $31.99:

1. 15%=10%+5%

2. To find 10% from $31.99 you should simply divide $31.99 by ten. Thus, 10% from $31.99 is $3.199.

3. 5% is half of 10%, then 5% from $31.99 is $3.199:2=$1.5995.

4. 15% from $31.99 is $3.199+$1.5995=$4.7985≈$4.80.

Answer: correct choice is B.

Solving for y right?

2y = 3x + 4 - x
2y = 2x + 4
y = 2x + 4 over 2
y = 2 (x + 2) over 2
y = x + 2


y - 3 = 2x - 6 over 2
y - 3 = 2(x - 3) over 2
y - 3 = x - 3
y = x


x - y - 2 = 2(2x + 1)
-y - 2 = 2(2x + 1) - x
-y = 2(2x + 1) - x + 2
y = -2(2x + 1) + x - 2
