Answer:
215; 8; 367
Step-by-step explanation:
231=7x+c
319=18x+c
c=The amount from bake sale (since it doesn't changes throughout the car wash)
x=$ earned per car
319=18x+c
-(231=7x+c)
Use elimination and subtract the values to get rid of a variable.
(319-231, 18x-7x, c-c)
88=11x
x=88/11
x=8
∴ The soccer team earns $8 per car.
231=7*8+c
231=56+c
c=231-56
c=175
∴ The soccer team made $175 from the bake sale.
The ans. is per blank from top ro bottom
1. c+5x=175+5*8
175+40 = 215
2. 255=c+?x
255=175+?*8
255-175=?*8
80=?*8
?=80/8
The soccer team washed 8 cars n earned $255
3. c+24x=175+24*8
175+192= 367
The soccer team earned $367 after 24 cars.
The linear equation that represents the scenario is 5x + 2.5y = 20
<h3>How to determine the equation?</h3>
The given parameters are:
- Popcorn = $5 per bag
- Candy = $2.5 per bag i.e. half the price of pop corn
Let x represents popcorn and y represents candy.
So, we have:
5x + 2.5y = 20
The intercepts in this case are the maximum number of candy and popcorn Rhonda can buy

#SPJ1
is comounded yearly formula
rat ie 4.5%
P=47000
solve for when A=63000
divide both sides by 47000
take the ln of both sides
divide both sides by ln(1.045)
using calculator
6.656=t
so after about 6.7 years
