Question

a photographer has 800 to spend on photo paper. Glossy photo paper costs 30 per box and standard paper costs 10 per box. If she has to buy 20 boxes of glossy photo paper, how many boxes of standard photo paper can she afford with the remaining money?

Answer 1

Answer:

20

Explanation:

number of glossy paper = 20

cost of 1 glossy paper = 30

hence, cost of 20 glossy paper = 30*20=600

money spent on paper= 800

cost of glossy paper = 600

hence, cost of standard paper= 200

cost of 1 standard paper = 10

total cost of standard paper = 200

hence, total number of standard paper= 200/10=20

Answer 2

Given: Money available = Rs 800

Glossy photo paper cost = Rs 30 per box

Standard paper costs = Rs 10 per box

Buying 20 boxes of glossy paper = $20\times 30$

                                             $= Rs 600$

Remaining money = $800-600= Rs 200$

Boxes of standard paper she can afford = $\frac{200}{10}$

                                              $=20 boxes$

So she can afford 20 boxes after buying glossy boxes.
