Answer:
6.25-1.75
Step-by-step explanation:
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
Number of dollars spent on the book = Amount she had - amount ended
Number of dollars spent on the book=
6.25-1.75
