This question is not correct because one of its options was not written correctly.
Correct question:
Jackie bought a 3-pack of tubes of glue. She used 0.27 ounce of the glue from the 3-pack
and had 1.35 ounces left in total. Which describes a way to determine the number of ounces
sold in each tube of glue?
a) Solve for x in the equation 3x - 0.27 = 1.35.
b) Divide 1.35 by 3 and then subtract 0.27 from the quotient.
c) Subtract 0.27 from 1.35 and the divide the difference by 3.
d) Solve for w in the equation 3 (x - 0.27) = 1.35.
Answer:
a) Solve for x in the equation 3x - 0.27 = 1.35.
Step-by-step explanation:
From the question we are told that 0.27 ounces of glue was sold from a 3 pack glue and we have 1.35 ounces of glue left in total.
The first step would be represent the 3 pack of glue as 3x where x represents each pack of the glue.
Therefore, mathematically, we have the Algebraic equation:
3x - 0.27 = 1.35..... Equation 1
This is because when we solve for x, we would be able to find the number of ounces sold in each tube.
Solving for x in the equation 3x - 0.27 = 1.35.
3x - 0.27 = 1.35.
3x = 1.35 + 0.27
3x = 1.62 ...... Equation 2
3x = The three pack tube containing the glue.
Where x represents each of the tubes.
This means, the three pack tube contained 1.62 ounces of glue.
To find out he amount of glue sold from each pack, we go back to our equation 2
3x = 1.62
x = 1.62 ÷ 3
x = 0.54 ounces.
This means from each tubes, 0.54 ounces of glue was sold.
Therefore, Option a) "Solve for x in the equation 3x - 0.27 = 1.35" is correct.
