Answer:
s = -2400t + 17400
Step-by-step explanation:
Let's say t is the x value on a coordinate plane, and s is the y. Then, we have the points (0, 17400) and (6, 3000). The slope of these is 14400/-6 or -2400.
Now we just have the equation y = -2400x + b, and from the point (0, 17400) we can find that b is 17400. So, we have y = -2400x + 17400. Convert these back into t and s and you get your answer, s = -2400t + 17400.

Step-by-step explanation:
Amount of yards of fabric for the shawl = 2 1/2
Amount of yards of fabric for the dress = 1 3/4
Total amount of yards needed
= 2 1/2 + 1 3/4
= 2 2/4 + 1 3/4
= 3 5/4
= 3 + 1 1/4
= 4 1/4
Since she has 3 yards of fabric, the number of yards needed more will be:
= 4 1/4 - 3
= 1 1/4
If each yard = 7.98, the amount needed will be:
= 1 1/4 × 7.98
= 1.25 × 7.98
= 9.975
