Answer:
Cost of Dinner = 50t + 7c + 475
Step-by-step explanation:
"t" represents tables and they cost $50 each, so the algebraic expression would be "50t" ($50 times the number of tables).
Same applies to chairs; "7c" ($7 times the number of chairs).
The $475 represents the other costs added to the total.
So the expression to represent this problem would be at the total cost of the charity dinner is 50t (50 dollars per table) plus 7c (7 dollars per chair) and $475 for other costs.
To do that is by the number 12 and is 12. and the 5 tenth is . 5 then put them together equals 12.5
