A standard shower head in Marty's house dispenses 7 gallons of water per minute. Marty changed this shower head to an energy-saving one. The equation shows the amount of water dispensed, y, as a function of the number of minutes, x, for the new shower head.

y = 3x

How much water does Marty save each day with the change in shower heads if he uses the shower for 8 minutes each day?

A. 4 gallons
B . 12 gallons
C . 32 gallons
D . 53 gallons

The standard shower head, if used for 8 minutes a day, will use up 56 gallons by the end of the day. The energy saving one will only use up 24 gallons by the end of the day if it is used for eight minutes. Take 24 and subtract it from 56. The difference of 24 and 56 is 32 (56-24=32). So the answer is C, 32 gallons.

The 32 gallons of water Marty saves each day with the change in shower heads if he uses the shower for 8 minutes each day option (C) is correct.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

A standard shower head in Marty's house dispenses 7 gallons of water per minute.

Marty changed this shower head to an energy-saving one.

The equation shows the amount of water dispensed, y, as a function of the number of minutes, x, for the new shower head:

y = 3x

Plug x = 8 minutes

y = 3(8)

y = 24

Now,

= 56 - 24

= 32

Thus, the 32 gallons of water Marty saves each day with the change in shower heads if he uses the shower for 8 minutes each day option (C) is correct.
