c+t=24
what is c

Answer 1

what do I do from here @pinkbubbles

Answer 2

here's the word problem
Alex stocks up for winter. He buys 24 cans of vegetables. He pays 80 cents per can for tomatos and 40 cents per can for corn, for a total cost of $12.8

Answer 3

\[\text{Solve}[\{0.8 c+0.4 t=12.8,c+t=24\}] \]Work it out.
c should equal 8 .

Answer 4

but how do I work it out

Answer 5

c + t =24, thus, t = 24 - c
Plug 24-c for each occurrance of t in the first equation and solve the result for c.

Answer 6

so then it would be 3?

Answer 7

Sorry, occurrance should have been spelled, occurrence.

Answer 8

so u said that c would equal 8 then wouldn't t equal 3

Answer 9

0.4 (24 - c) + 0.8 c = 12.8
0.8 c - 0.4 c + 9.6 =12.8

Answer 10

so what do I do next

Answer 11

0.4 c = 12.8 - 9.6
0.4 c = 3.2
c = 8

Answer 12

so how did u get 9.6

Answer 13

so is 8 the answer or the value of c

Answer 14

0.4 (24 - c) + 0.8 c = 12.8
9.6 + 0.8 c = 12.8

Answer 15

"so is 8 the answer or the value of c ? "
Yes.

Answer 16

so the answer would be 16 right
