#We now calculate the patio's area in sq ft:
#To determine the total cost of the pavers, we multiply by the cost per sq foot;
Hence, the pavers cost a total of $268.80
Answer:
Step-by-step explanation :
N = number of nickels
D = number of dimes
Q = number of quarters
`
252 = N + D + Q <---- Equation 1
D = 3(N+Q) <---- Equation 2
24.85 = 0.05N + 0.10D + 0.25Q <---- Equation 3
We a have set of three linear equations to solve for three unknowns N, D, and Q.
Rearranging the equations we have :
N + D + Q = 252
3N - D + 3Q = 0
0.05N + 0.10 D + 0.25Q = 24.85
Solving the set of linear equations, we end up with :
N = 49
D = 189
Q = 14
