Answer:
n = 12 nickels
d = 11 dimes
q = 7 quarters
Step-by-step explanation:
.05n + .1d + .25q = 3.45
n + d + q = 30
n = q + 5
n = 12
d = 11
q = 7
Answer:
x=2.5&.5
Step-by-step explanation:
The quadratic formula is (-b+or-sqrt(b^2-4ac)/2a
12+or-sqrt((-12^2)-4(4)(5))
12+or-sqrt(144-80)
12+or-sqrt(64)
(12+8)/8 and (12-8)/8
x=2.5 and x=.5
The final answer is : z >_ -2
So there's 6 bottles and each bottle costs 3.60 but there's 4 cases.
So first multiply the number of bottles which is 6 with the cases which is 4.
6 x 4 = 24,so there's 24 bottles.Now multiply the price of the bottles time 24.
24 x 3.60 = 86.4.So the person that bought that will have to pay 86.4.Man those things are expensive.
Hope this helps :D
