The Wonder Wings Insect Museum sells bug-shaped notebooks in their gift shop. Last month, they sold 35 butterfly notebooks and 55 ladybug notebooks. The notebooks were so popular that they want to order more this month. They plan to order 110 ladybug notebooks this month.
If they keep the same ratio, how many butterfly notebooks should they order this month?
To find the number of butterfly notebooks they should order this month, you need to set up a proportion based on the ratio of butterfly notebooks sold to ladybug notebooks sold.
The proportion is:
35 butterfly notebooks / 55 ladybug notebooks = x butterfly notebooks / 110 ladybug notebooks
To solve for x, you cross-multiply:
55x = 35 * 110
And then divide both sides by 55:
x = (35 * 110) / 55
Simplifying the expression on the right side:
x = 3500 / 55
x = 63.636
They should order approximately 64 butterfly notebooks this month.
