Answer:
4.25 feet of ribbon cost around $ 8.29
Step-by-step explanation:
We are given the following information in the question:
Length of ribbon to be bought by Brenna = 4.25 feet
Cost of 1 foot of ribbon = $1.95
Total or actual cost of the ribbon =

Cost of ribbon to be purchased by Brenna =


Thus, to find the actual cost Brenna should use the product of total length of ribbon to be bought and the unit cost of the ribbon.
Hence, 4.25 feet of ribbon cost around $ 8.29
Answer:
Step-by-step explanation:
Let the money earned during fundraising activities =x
Since the World Issues club has decided to donate 60% of all their fundraising activities this year to Stephen Lewis Foundation.
The amount of money the foundation will receive
=60% of x
= 0.6x
In the bake sale, the club raised $72.
Therefore, the amount the foundation will receive =0.6*72=$43.20
At the end of the year, the World Issues Club mailed a cheque to the foundation for $850.
Therefore:
0.6x=850
x=850/0.6
x=$1416.67
The total amount of money the club raised is $1416.67.
