Diana and Sue clean homes for a summer job.The charge 70$ per house plus 15%tip. If they clean 3 house per week how much tip do,
jek_recluse [69]

Diana and sue made $ 241.5 per week

<em><u>Solution:</u></em>

Given that Diana and Sue clean homes for a summer job

The charge 70$ per house plus 15% tip

charge = $ 70 plus 15 % tip

So 15 % tip is made for $ 70

<em><u>charge per house is given as:</u></em>

charge per house = 70 + 15 % of 70

\rightarrow 70 + 15 \% \times 70\\\\\rightarrow 70 + \frac{15}{100} \times 70\\\\\rightarrow 70 + \frac{15}{10} \times 7\\\\\rightarrow 70 + 1.5 \times 7 = 70 + 10.5 = 80.5

Thus charge per house is $ 80.5

<em><u>If they clean 3 house per week, then the total charge is:</u></em>

charge for 3 house = charge for 1 house x 3

\text{ charge for 3 house} = 80.5 \times 3 = 241.5

Thus Diana and sue made $ 241.5 per week
