Answer:
1 is b and 2 is a
Step-by-step explanation:
The answer is straightforward, by the "rule of product":
There are
3×8×2=48
3×8×2=48
different combinations (distinct possible cars) that can be created.
There 33 choices for body style; 88 choices for exterior colors, and 22 choices of interior color schemes:
Since each of these choices are independent (the choice of body style doesn't depend on exterior or interior color, e.g.) we multiply the number of choices for each quality to obtain: 3×8×2=483×8×2=48 distinct ways to create a car
Let x and y be the rate per hour for Mechanic 1 and 2 respectively.
Then,
x+y=205 ---------- (1)
Additionally,
10x+15y = 2500 ------ (2)
Solving equations 1 and 2;
Multiply (1) by 10 and subtract two from the result,
10x+10y = 2050
10x +15 y =2500
----------------------
-5 y = --450 => y = 450/5 = $90
Then,
x= 205-90 = $115
Therefore,
Mechanic 1 charged $115 per hour
Mechanic 2 charged $90 per hour
80% of (Cost) = $68
80% is also 0.8:
0.8 x Cost = $68
dividing each side by 0.8
Cost = 68 / 0.8 = 85 = $85
Answer:
Expression is:16n+2.50
For buying 4 tickets: 66.50
Step-by-step explanation:
You first have to set up the equation and each ticket cost 16 and you have to buy sixteen that is why it is 16n and then you have to pay 2.50 because you are buying online. Then you put four in for N because you are getting 4 tickets. Finally multiply 16 and 4 then add 2.50.
