The ratio of white pens to blue pens in jakes drawer is 4 to 3. If Jake has more than 40 pens, what is the minimum number of pens that can be in jakes drawer?
The minimum number of pens that can be in Jake's drawer is 70 pens.
we can do like this
3:4
add them
3+4=7, not over 70
hmm
one way is
3+4=7
how many 7's are more than 40
7x>40
divide both sides by 7
x>5.7
about 6
36=18
46=24
18:24 is the minimum ratio
18+24=42
minimum number of pens is 42
