A yard cleanup service charges a $345 fee plus $16.25 per hour. Another cleanup service charges a $213 fee plus $24.50 per hour.
Thepotemich [5.8K]

The time for the job for which the two company are the same is 16

<h3>How to form the equation and find the cost?</h3>

A yard cleanup service charges a $345 fee plus $16.25 per hour. Therefore,

using linear equation,

y = mx + c

where

  • y = total cost
  • x = time

Therefore,

y = 345 + 16.25x

Another cleanup service charges a $213 fee plus $24.50 per hour. Therefore,

y = 213 + 24.50x

Hence, the time when both cost are the same is as follows;

213 + 24.50x =  345 + 16.25x

213 - 345 = 16.25x - 24.50x

-132 = -8.25x

x = 132 / 8.25

x = 16

kvv77 [185]
<h3><u>Answer:</u></h3>

\boxed{\boxed{\pink{\bf The \ two \ numbers \ are \ 12  \& \ 85 . }}}

<h3><u>Step-by-step explanation:</u></h3>

Given that , One number is 1 more than 7 times the other number. If their sum is 73 more than

twice the smaller number. And we need to find the numbers. So let us take the

  • First Number be x .
  • Second number be 7x+1 .

\underline{\red{\boldsymbol{ According \ to \ the \ Question :- }}}

\bf\implies 2( Small \ no.) + 73 = Bigger \ no. + Smaller \ no.\\\\\bf\implies 2x + 73 = x + 7x + 1\\\\\bf\implies 2x + 73 = 8x + 1 \\\\\bf\implies 8x - 2x = 73-1 \\\\\bf\implies 6x = 72 \\\\\bf\implies x =\dfrac{72}{6}  \\\\\bf\implies \boxed{\red{\bf x = 12 }}

Hence the smaller number is 12 and the bigger number will be :-

\bf \implies Number_{bigger} = 7x + 1 \\\\\bf\implies Number_{bigger} =7(12)+1\\\\\bf\implies Number_{bigger} = 84 + 1 \\\\\bf\implies \boxed{\red{\bf Number_{bigger}=85 }}

<h3><u>Hence </u><u>the</u><u> </u><u>bigger </u><u>number</u><u> </u><u>is</u><u> </u><u>8</u><u>5</u><u> </u><u>and</u><u> </u><u>the </u><u>small</u><u>er</u><u> number</u><u> </u><u>is</u><u> </u><u>1</u><u>2</u><u>. </u></h3>
