Let's make a system of equations to solve for this:
n + q = 84
0.05n + 0.25q = 12.80
where n = nickels and q = quarters.
---
Solve for n in the first equation by subtracting q from both sides.
n = 84 - q
---
Plug n into the second equation.
0.05(84 - q) + 0.25q = 12.80
Distribute 0.05 inside the parentheses.
4.2 - 0.05q + 0.25q = 12.80
Combine like terms.
4.2 + 0.2q = 12.80
Subtract 4.2 from both sides.
0.2q = 8.6
Divide both sides by 0.2.
q = 43
---
Plug 43 for q in the first equation.
n + (43) = 84
Subtract 43 from both sides.
n = 41
---
There are 41 nickels and 43 quarters in the piggy bank. ✅

Answer:
Alicia pagara MX$1,700.
Step-by-step explanation:
A 32% discount (descuento) would come to 0.32(MX$2,500) = MX$800.
Subtracting MX$800 from MX$2,500 yields MX$1,700.
Alicia pagara MX$1,700.
X-3y=9
-3y=-x+9
Divide by -3
Y=1/3x+3
Slope is 1/3x
Y intercept is 3
X intercept is 9
(24% ÷ 100) × 8440= 2025.6
now we round 2025.6 which is 2026 employees
ANOTHER METHOD WOULD BE:
24% × 8440 = 2025.6 rounded to 2026
or 0.24 × 8440 = 2025.6 rounded to 2026
