Jerry takes 0.75 hours or \frac{6}{8} hours more to clean house than thomas

<h3><u>Solution:</u></h3>

Given that Jerry and Thomas own a cleaning business

Thomas cleans a house in 2\frac{1}{2} hours and Jerry cleans a house in 3\frac{1}{4} hours

To find: Number of hours more Jerry takes to clean than thomas

<em>Number of hours more Jerry takes to clean than thomas = time taken by Jerry - time taken by thomas</em>

Time taken by Jerry = 3\frac{1}{4} = \frac{3 \times 4 + 1}{4} = \frac{13}{4} \text{hours}

Time taken by Thomas = 2\frac{1}{2} = \frac{2 \times 2 + 1}{2} = \frac{5}{2} \text{hours}

Substituting the values in above formula,

Number of hours more Jerry takes to clean than thomas = \frac{13}{4} - \frac{5}{2}

On solving we get,

=\frac{13}{4} - \frac{5}{2}\\\\= \frac{26-20}{8}\\\\= \frac{6}{8} = 0.75

Thus Jerry takes 0.75 hours or \frac{6}{8} hours more to clean house than thomas

If a line is parallel to another line,Then the gradients are the same.So m=4 .Using general formula for str8 line, y=mx+c
y = 4x + c
sub in coorfinates (1,13)
13  = 4 + c
So C=9.
y = 4x + 9
