1) Assuming the number of crayons in a box, if Bob paid $ 9.90 for a box of crayons, the cost of each crayon in the box is $0.825.
2) The value of y in the given equation {8y + 3= 6y + 9} is 3.
1) How much did each crayon cost?
Given that;
- Bob paid $ 9.90 for a box of crayons.
- Assuming each box contains 12 crayons.
- Cost of each crayon = ?
To determine the cost of each crayon;
12 crayons = 9.90
1 crayon = x
x = 9.90 / 12
x = 0.825
Assuming the number of crayons in a box, if Bob paid $ 9.90 for a box of crayons, the cost of each crayon in the box is $0.825.
2) What is the value of y in the equation?
Given the equation: 8y + 3= 6y + 9.
We solve for the value of y.
8y + 3 = 6y + 9
Collect like terms
8y - 6y = 9 - 3
Subtract 6y from 8y and 3 from 9
2y = 6
Divide both sides by 2
2y/2 = 6/2
y = 3
Hence, the value of y in the given equation is 3.
