Question

You can buy 20 photocards for 30$ how much will it cost you to buy 55 photocards

Answer 1

`\huge\boxed{\sf \$ 82.5}`

Explanation:

Given that,

20 photocards = $30

Using unitary method

• Divide 20 to both sides

20/20 photocard = $30/20

1 photocard = $1.5

• Multiply 55 to both sides

1 × 55 photocards = $1.5 × 55

55 photocards = $82.5

`\rule[225]{225}{2}`
