Chapter 3: Q. 190 (page 352)

Hector spent $$33.20$ at the post office. He bought four times as many role="math" localid="1647145644364" $$ 0.41$ stamps as $$ 0.02$ stamps. How many of each did he buy?

Short Answer

Expert verified

First stamp with cost $0.41 $$ is $80$ and second stamp with cost $0.02 $$ is $20$

Step by step solution

Step 1. Given information

Hector spent $33.20 $$ at the post office. He bought four times as many stamps as $0.02 $$ stamps.

Step 2. Let the number of stamps be x,

Now, $4$ times as many as $0.41 $$ stamp becomes $0.41 x$

and role="math" localid="1647145841238" $0.02 $$ becomes $0.02 x$

Step 3. Making equation and solving it we get

$(0.41) 4 x + 0.02 x = 33.20 1.64 x + 0.02 x = 33.20 1.66 x = 33.20 x = 20$

Hence no. of stamp of cost $0.41 $$ is $4 \times 20 = 80$

no. of stamps of cost $0.02 $$ is $20$
