Answer:

1008

Step-by-step explanation:

Allen=A

Bob=B

Jane=J

So what we know is 

A=4B

J=2A

A+J=432

What we want to know is

A+J+B=?

So we need to solve for B

The easiest way would be to substitute into the A+J equation so

A+(2A)=432

3A=432

A=144

And we know that 4A=B so 4(144)=B thus B= 576

So 432+576=1008!

Boots: $59.00, discount: 10 percent sales tax 5.5 percent
I am Lyosha [343]

Answer:

Total cost of boots = $56.02

Step-by-step explanation:

$59 x 0.90 = $53.10

$53.10 x 1.055 = $56.02

or

59 x 0.10 = 5.9

59 - 5.9 = $53.10

53.10 x 0.055 = $2.92 tax

$53.10 + $2.92 = $56.02
