Answer:
$54.25
Step-by-step explanation:
4/5 yards of lace = $5.60
Price per yard = 5.60 ÷ 4/5
= 5.60 × 5/4
= 28 /4
= $7 per yard
The class decided to buy another 7 3/4 yd
Cost of 7 3/4 yd = cost per yard × number of yards
= $7 × 7 3/4
= $7 × 31/4
= 217 / 4
= $54.26
Cost of 7 3/4 yd = $54.25
Answer:

Step-by-step explanation:
You start noticing that for x = 9 g(x) =0, and for x= -7 the function isn't defined.
That splits the number lines in 3 areas: x<-7; -7<x<9, and x>9. (notice the strict inequalities since we already discussed the breaking points.
Let's try a point in each interval, namely, since i like the values, -10, 0, 10.

We have all the informations we need. The value we need are 
The simple interest earned in year 1 is 7.5. The simple interest earned in year 1 is $7.50. The total interest earned at the end of year 4 is $30.00
<h3>How to calculate a simple interest amount?</h3>
If the initial amount (also called as principal amount) is P, and the interest rate is R% annually, it is left for T years for that simple interest.
3% simple annual interest paid on $250
A 2-column table with 4 rows.
Column 1 is labeled Year with entries 1, 2, 3, 4.
Column 2 is labeled Total Interest Paid with an entries question mark, 15 dollars, 22 dollars, and 50 cents,
The simple interest earned in year 1 is calculated as
The first one is (0.03)(250) = 7.5
The simple interest earned in year 1 is
The second one is $7.50
The total interest earned at the end of year 4 is
The third one is $30.00
