Question 569896: I have an assignment for solving inequalities. I had to write an expression that would represent the cost of any amount of ceramic tile given that ceramic tile costs $2.00 per square ft. (use variable c to represent a square foot of ceramic tile). Do not write an equation. My answer to this was $2.00 per square ft=2c.
Write an expression that would represent the cost of any given amount of the decorative tile given that decorative tile costs $5.00 per square ft. (use variable d to represent a square ft of decorative tile). I wrote $5.00 per square ft=5d
Would you please let me know if this is correct because there still are 10 more parts to this and I have to write them as inequality equations.

but I don't understand how to get to that.

Question 562761: To buy both a new car and a new house, Tina sought two loans totalling $321,929. The simple interest rate on the first loan was 1.0%, while the simple interest rate on the second loan was 8.8%. At the end of the first year, Tina paid a combined interest payment of $25,677.83.

I think i know the expression and answer but not sure how to work it out
.01x + .088(321929-x) = 25677.83
x=33,999
(321929-x)=287,930
Answer: first loan (x)=$33,999 .....second loan (321929-x)=287,930
