QuestionA plumber charges \ $80 plus \$25 per hour. If the bill is \$160, which equation represents this? <br />1.$ 80 h + 25 = 160 $<br />2.$ 80 + 25 h = 160 $<br />3.$ 80(h + 25) = 160 $<br />4.$ 25(h + 80) = 160$

Studdy Solution

STEP 1

Assumptions1. The plumber charges a fixed service charge of $80. . The plumber also charges$ 25 per hour of work.
3. The total bill for a repair is $160.<br />4. The variable$ h$ represents the number of hours the plumber worked.

STEP 2

We need to form an equation that represents the total charges. The total charges are made up of the fixed service charge and the hourly charges. $Total\, charges = Service\, charge + Hourly\, charges$

STEP 3

Now, plug in the given values for the service charge and hourly charges to form the equation. The hourly charges are calculated by multiplying the rate per hour ( $25) by the number of hours ($ h$).
$Total\, charges = \$80 + \$25h$

STEP 4

We know that the total charges amount to $160. Therefore, we can set our equation equal to$ 160$.
$\$80 + \$25h = \$160$ So, the equation that represents the charges is $80 +25h =160$ .
