Answer:≈2.67
Step-by-step explanation:
To figure this problem out, we must first figure out what a single piece of candy costs. So we take the total cost of the three candies and divide that number by the number of candies, or:
4/3,
to give us the number 1.3 repeating. This means that a piece of candy would cost $1.33. We multiply this by two to get approx. 2.67, or $2.67.
Hope that helped.
Answer:
y = 10x.
Step-by-step explanation:
Hayley is considering two gym membership plans. The plans are detailed here.
Plan One: $50 for a monthly pass plus $3 for each gym visit
Plan Two: $10 for each gym visit.
Therefore, if variable y is the total cost and x variable is the number of gym visit per year, then y will be given in the plan two by the equation
y = 10x ........ (1) (Answer)
Answer:
We simplify the equation to the form, which is simple to understand
5x+25=10
We move all terms containing x to the left and all other terms to the right.
+5x=+10-25
We simplify left and right side of the equation.
+5x=-15
or this is another way
Simplifying
5x = 25 + -10
Combine like terms: 25 + -10 = 15
5x = 15
Solving
5x = 15
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Divide each side by '5'.
x = 3
Simplifying
x = 3
We divide both sides of the equation by 5 to get x.
x=-3
Answer:
a). Nadia made a total of $825 last week in commission sales
b). The total amount Nadia in commission in 2011=$42,900
Step-by-step explanation:
Step 1
Express the amount in commission she earns from her sales as follows;
C=S×r
where;
C=commission earned
S=total value of stock sales
r=commission rate
In our case;
C=unknown
S=$7,500
r=11%=11/100=0.11
replacing;
C=11% of 7,500
C=(11/100)×7,500
C=0.11×7,500=825
Nadia made a total of $825 last week in commission sales
b). To express the total amount she made in 2011, we derive the formula below;
Total amount (2011)=Average weekly commission×number of weeks in 2011
where;
Average weekly commission=$825
number of weeks in 2011=52
replacing;
Total amount (2011)=(825×52)=42,900
The total amount Nadia in commission in 2011=$42,900
(P+T)-7 = 6. 7 less than, meaning taking away 7 from the sum of (P + T) is as much as / equal to 6
