Answer:
4
Step-by-step explanation:
To solve this problem, you will need to set up a proportion.
Let x = the unknown cost of the books.
Assuming the cost of books stays constant, you can crossmultiply and solve for x.
x = 1.95(6)
x = 11.70
Six books will cost $11.70 if 1 book cost $1.95.
Answer: 4.6 (rounded to the nearest tenth)
Step-by-step explanation:
I assume that 1.6 is the coefficient of x, which is what we're trying to find out in this case.
Therefore, dividing 1.6 on both sides we get
from
1.6x = 7.37
to
x = 7.37/1.6 = 4.6 (approximately, rounded to the nearest tenth).
