1.) A pipe bursts in your house and you call 2 plumbers for estimates. Plumber A says he charges $40 to check the problem and $ 55 an hour to repair. Plumber B says he
charges $ 60 to check the problem and $ 40 an hour. If the repair takes 4 hours to
complete, which plumber would be a better option.

Plumber B

Step-by-step explanation:

Plumber A: First, multiply $55 times 4, then add the fee of $40. This will give you $260 as total. This is how much it would cost for Plumber A.

Plumber B: Multiply $40 by 4 and then add $60. This gives you $220, showing that Plumber B is a better option.

Plumber B

Step-by-step explanation:

We could set up 2 expressions, and set the time to be 4 hours, and see which plumber costs less:

Plumber A: 40+55*4 = $260

Plumber B: 60+40*4 = $220

Plumber B is cheaper, so therefore he/she is the better option.

answer: a

step-by-step explanation:

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
