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?
Plz help with this question. Thank you!
This did not help me at all
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
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.
Thank you so much Mr Scott and Henry for taking time to explain in steps!!!

To solve this problem, we need to find the individual prices of tables and chairs.
First, let's assume the cost of each chair is 'x'. Since each table costs three times as much as each chair, the cost of each table would be 3*x.
According to the given information, Bob paid $1210 for 5 tables and 7 chairs.
So, we can create an equation based on the total cost:
5 * (3*x) + 7 * x = $1210
Now, let's solve this equation to find the value of 'x', which represents the cost of each chair.
15*x + 7*x = $1210
22*x = $1210
x = $1210 / 22
x ≈ $55.00
We found that the cost of each chair is approximately $55.00.
Next, we can calculate the cost of each table:
3 * x = 3 * $55.00 ≈ $165.00
So, each table costs approximately $165.00.
Now, let's calculate the total amount Ann would have to pay for 8 tables and 4 chairs:
Total cost for tables = 8 * $165.00 = $1320.00
Total cost for chairs = 4 * $55.00 = $220.00
Therefore, Ann would have to pay approximately $1320.00 + $220.00 = $1540.00.
