Anita and Maria went to the candy store. Maria bought 5 pieces of fudge and 3 pieces ofbubble gum for a total of $5.70. Anita bought 2 pieces of fudge and 10 pieces of bubblegum for a total of $3.60. Determine the cost of 1 piece of bubble gum.
Answers
Final answer:
The price of one piece of bubble gum is $0.15. This can be determined by setting up algebraic equations based on the given information, allowing the fudge and bubble gum prices to be calculated.
Explanation:
The subject of this question is algebra and it uses a system of simultaneous equations to find the price of each piece of candy.
- Let's say 'f' is the cost of fudge and 'g' is the cost of gum.
- We can write two equations based on the information given: 5f + 3g = 5.70 and 2f + 10g = 3.60.
- To find the cost of the bubble gum first, we can eliminate 'f' by multiplying the first equation by 2 and the second one by 5 which will give us: 10f + 6g = 11.40 and 10f + 50g = 18.00
- Then we subtract the second equation from the first equation. This gives us: 44g = 6.60.
- Finally, we divide by 44 to get the price of gum, 'g' = 6.60 / 44 = $0.15.

The possible arrangement can be done as -
- 2 rows, with 8 chairs in each row.
- 4 rows, with 4 chairs in each row.
- 8 rows, with 2 chairs in each row.
What is a Arrangement? What is equation modelling? What is a mathematical equation and expression?
- Arrangement numbers, more commonly called permutation numbers, or simply permutations, are the number of ways that a number of things can be ordered or arranged.
- Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
- A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.
- A mathematical equation is used to equate two expressions.
Given is that a teacher wants to arrange 16 chairs in equal rows in his classroom.

75 percent off
100 percent=original
75 percent off=100-75=25%
160=25% of original cost
'of' means multiply
remember tha tpercent is parts out of 100 so
25%=25/100=1/4
160=1/4 times original cost
multiply both sides by 4
640=original cost
answe ris $640 =original cost
One simple trick here is that 25% is one third of 75%. So all you need to do is MULTIPLY $160 by 4 to get how much the camera's regular price was.
160 x 4 = 640
The camera's regular price was $640.00
