Answer:
73 dimes and 133 nickels
Step-by-step explanation:
$13.95 = 1395 cents
5n + 10d = 1395 (since each nickel is 5 cents and each dime is 10 cents)
5n = 1395 - 10d (subtract 10d from both sides to solve for n)
n = 279 - 2d
n + d = 206
279 - 2d + d = 206 (substitute n with the previous expression)
279 - d = 206 (add variable d and -2d)
-d = -73 (solve for d and divide both sides by negative 1)
d = 73
n + 73 = 206 (solve for n and subtract both sides by 73)
n = 133
Answer:
1. Figure 3
2. 2881.4 cm³
Step-by-step explanation:
The graph in figure 3 has a curve that fits the data best because it captures most of the points unlike the other two curves.
The curve in figure 3 has the equation;

2.
When using x=8, substitute the value of x in the equation with 8 to get
y = -16.9*64 + 430*8 + 523
y= 2881.4
= 2881.4 cm³
