Answer:
balloons= 9
candles= 8
Step-by-step explanation:
let the number of balloons be x
and candles be y
So
15x+8y=192----------1
x+y=17--------------2
from 2, x= 17-y
put x= 17-y in 1
15( 17-y)+8y=192
255-15y+8y=192
solve for y
-7y=192-255
-7y=-63
x=63/7
x=9
put x= 9 in 1
9+y=17
y= 17-9
y=8.
Answer:
$10000 Total cost to transport 14 tons
Step-by-step explanation:
The total cost C(S) = $6500 + ($250/ton)S. <em>This is a linear function with initial value $6500 and slope $250/ton.</em>
C(14) = $6500 + ($250/ton)(14) = <em>$10000 = Total cost to transport 14 tons</em>

Same thing applies to this answer as to the last answer I posted
Answer:
Distance traveled= 41968.4 km
The domain of the function is t
t(h)= 478
h = hours
Step-by-step explanation:
the distance that they traveled in kilometers, d, can be modeled by
d(t) = 97.8t
where t is the time in hours
They traveled a total of 478 hours.
Distance traveled d(t)
d(t) = 87.8(478)
d(t) = 41968.4
Distance traveled= 41968.4 km
The domain of the function is t
t(h)= 478
Answer:
84 juice bottles
Step-by-step explanation:
Given the ratio of grapefruit juice, pineapple juice, and tomato juice bottles as
3:1:2
Let the total number of bottles available be R
If there are 14 pineapple juice bottles, then
1/(3 + 1 + 2) * R = 14
1/6 * R = 14
multiply both sides by 6
R = 14 * 6
= 84
This means there are 84 bottles in all
