Answer:

Step-by-step explanation:

Amount paid for first 100 watches = (65% of 80) *100

                                                        =\frac{65}{100}*80*100\\\\= 65*80\\= 5200

Amount paid for next 50 watches = (55% of 80) * 50

                                                        = \frac{55}{100}*80*50\\\\= 55 * 8 * 5\\\\= 2200

Remaining watches = 280 -(100+ 55)

                                 = 280 - 155 = 125

Amount paid for 125 watches = (45% of 80) *125

                                                  = \frac{45}{100}*80*125\\\\= 45 * 20 * 5\\\\= 4500

Amount received by the watch maker = 5200 + 2200 + 4500

                                                               = £ 11900

Tom decides to paint one wall in his room green. Use the dimensions below to calculate the area of the this wall.
Anton [14]

Option C:

Area of the wall =94\frac{15}{16} square feet

Solution:

Length of the wall = 12 \frac{1}{4} feet

Width of the wall = 7 \frac{3}{4} feet

Area of the wall = length × width

                          $=12 \frac{1}{4}\times 7 \frac{3}{4}  

Convert mixed fraction into improper fraction.

                          $=\frac{12 \times 4+1}{4}\times  \frac{7\times 4+3}{4}

                          $=\frac{49}{4}\times  \frac{31}{4}

                          $=\frac{1519}{16}

Convert improper fraction into mixed fraction.

                          $=94\frac{15}{16}

Area of the wall =94\frac{15}{16} square feet

Option C is the correct answer.

Step-by-step explanation:

To find proportionality, solve for 8.5 divided by 2 and 17 divided by 4.

Both of those answers are 4.25, so that would be the final answer.
