bob paid $1210 for 5 tables and 7 chairs for his company. each table costs three time as much as each chair. of ann bought 8 such table and 4 such chairs. how much money would she has to pay?

Question

Plz help with this question. Thank you!

Answer 1

5 t + 7 c = 1210

t = 3 c

substituting ... 5 (3 c) + 7 c = 1210 ... 22 c = 1210

solve for c , then substitute back to find t

ann needs ... 8 t + 4 c

Answer 2

Each chair cost $X.
Each table cost $3x.
7x + 5*(3x) = 1210,
X = $55.
3x = 3 * 55 = $165.

8*165 + 4*55 = Amt. Anne needs.
