Cloth cost is based on its area
Here napkin costs $3.25
A similar tablecloth is 5 times longer and 5 times wider. S its area is 25 times the area of the napkin. So its cost will also be 25 times of the cost of napkin
<span><span>Cost of Tablecloth=$3.25×25=$81.25</span></span>
Answer:
This is a function y = mx + b:
- You start with $50, so the y-intercept(b) is 50.
- Adding $20 a week means that the slope(m) is 20.
So, the function would be y = 20x + 50, where y is the dollar amount after x weeks and x cannot be greater than 12.
Assume the sum is 100. The ratio of the two numbers is 15:10. This means that we can divide this indow 15+10, or 25 parts. Let us do that. Divide 100 into 25 parts and see how much is in each part. 100/25 is 4, meaning that there is 4 in each part. 15 parts will have 15*4, or 60. 10 parts will have 10*4, or 40. To confirm, add 40 and 60. It matches with what we started out with, 100.
The two numbers, assuming the sum is 100, are 40 and 60. 60 is the greater value.
