1.) B
because it says the person buys a ski for 350. He puts down $110 which means to subtract. Now he got a discount which also means to subtract. Then it told that he gave 1/2 them money to his mother. So that too means to subtract.
2.) 2+5n
because it says 2 plus 5 times a number. So 2+5×n
Answer:

Step-by-step explanation:
This is horizontal parabola.
It has a directrix at x=-6.
The vertex is (0,0).
The focus is (6,0)
The equation of this parabola is of the form

Where (p,0) is the focus
By comparison, p=6
Therefore the equation of the parabola is

This implies that

The expression would be (5*6)+(5*6)=x
or you could shorten it and do (10*6)=x
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Cost of large candle (a) = 25 each
Cost of small candles (y) = 10 each
Amount needed = $600
Number of each that must be sold to raise needed amount:
25a + 10y = 600.
Here a = number of large candles that must be sold at the price
y = number of small candles that must be sold at the price
Summing the revenue both should result in the required amount.
