If refreshments cost 45$ for 18 people, at the same rate, how much would refreshments cost for 26 people?
Use this proportion. Cross multiply and solve for x.
45/18 = x/26
18x = 1170
x = $65
Thanks Ms.sue, this is really helpful! :)
You're very welcome, Lilly.
To find out how much refreshments would cost for 26 people, we need to calculate the cost per person and then multiply it by the number of people.
Given that refreshments cost $45 for 18 people, we can determine the cost per person by dividing the total cost by the number of people.
Cost per person = Total cost / Number of people
Cost per person = $45 / 18 people
To calculate this, we divide $45 by 18:
Cost per person = $2.50
Now that we know the cost per person is $2.50, we can find the total cost for 26 people by multiplying the cost per person by the number of people:
Total cost for 26 people = Cost per person * Number of people
Total cost for 26 people = $2.50 * 26 people
To calculate this, we multiply $2.50 by 26:
Total cost for 26 people = $65
Therefore, refreshments would cost $65 for 26 people at the same rate as the initial cost for 18 people.
