Answer:
1.09×10^2
Step-by-step explanation:
................
The general equation is that for every red tile, there must be 12 blue ones.
Algebraically this is expressed as b = 12r where r is red and b is blue. Your teacher might like you to express it as y = 12x where y is blue and x is red. The meaning is the same.
For beginners it might be easier to say b = 12r. So if you have 15 reds then r = 15
b = 12 * r
b = 12 * 15
b = 180 blue tiles.
That is approximately, in order, a C, a C, a B, a D, an A, a B, and an A.
In grade points that is a 2, a 2, a 3, a 1, a 4, a 3, and a 4.
The average of those numbers is about 2.7, so you have a 2.7.
You can raise that by bringing up the D as it is an outlier here.
