Question

Monique had 6 dollars. She found 25 cents and then bought a book. She ended up with 7 quarters. Which expression equals the number of dollars Monique spent on the book?

Answer 1

Answer:

$6.25-1.75$

Step-by-step explanation:

Monique had 6 dollars. She found 25 cents and then bought a book

25 cents = 0.25 dollars

Total dollar she had= 6 + 0.25= 6.25 dollars

Let x be the cost of a book

She ended up with 7 quarters. Convert quarter into dollars

1 quarter = 0.25 dollars

7 quarters = 7 times 0.25=1.75 dollars

So she ended up with 1.75 dollars

Amount she had at the beginning - the cost of book = amount ended up

$6.25 -x = 1.75$

Number of dollars spent on the book = Amount she had - amount ended

Number of dollars spent on the book=$6.25-1.75$

Answer 2

$6.25-(7x $0.25)

$6.25-$1.75=

Monique spent $4.50 on the book
