You do what is asked for in the parentheses then multiply by the number outside of them.
Answer: Well theres no table added but it probably looks like this
X Y
8mph 4 min
2mph 1 min
I think you can do the rest
The easiest way to think of these is to put them in terms of percentages. Obviously, if you are SAVING 25%, you are SPENDING 75%. So if she SPENDS 13.50, we can easily use the 75% in an equation. $13.50 = .75x, with x being what the shoes cost originally. The .75 indicates that she is spending 75% of what the original cost is. You don't have any examples to pick from, but this is the best way to explain what one of the equations could be. You could also base it on money saved, but the equation is not quite as neat.
Here's a list that might help:
Odd functions: sinx, tanx, cotx, cscx
Even functions: cosx, secx
Step-by-step explanation:
so, he will not wear any pants ? socks ? not to mention underwear ?
anyway, we have to deduct the $35 for the shoes, as he is seemingly buying them in any case.
so, we are left with 100 - 35 = $65 for shirts.
as one shirt costs $15, we need to see how often 15 fits into 65, as that is the answer how many shirts he can buy for this money.
65 / 15 = 4.333333333...
since he cannot buy a part shirt, we can only rely on the integer part of the calculation.
so, he can buy 4 shirts and will have $5 left.
