Question

Last month, the soccer team held a bake sale to raise money for new uniforms. They did not raise enough money, so they organized a car wash. The table below shows the number of cars washed and the total amount of money raised by the soccer team, including the amount raised from the bake sale. Fill in the empty values in the table (| | = the empty spaces, its hard to put it in a table format using only text)


Number of Cars Washed Total Amount Raised

5 $| |

7 $231

| | $255

18 $319

24 $| |

30 $| |

Answer 1

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.
