Answer:
Stefanie bought 10 erasers
Step-by-step explanation:
We can establish the following equation:
TP = NP*PP + NE*EP
Where:
TP = Total price; (4.25)
NP = Number of pencil packages; (1)
PP = Pencil Package's Price; (1.75)
NE = Number of erasers; (What we are looking for)
EP = Erasers Price; (0.25);
Then:
4.25 = 1*1.75 + NE*0.25;
4.25 - 1.75 = NE*0.25;
2.5/0.25 = NE;
10 = NE.
X^2 and 5x both have x in common to factor out. To add or subtract them, 5x^2 is the least common denominator .
False because you can subtract your way out of the set of whole numbers
P(B) = 0.75.
For independent events, P(A and B) = P(A)*P(B). This gives us
1/8 = 1/6(x)
Divide both sides by 1/6:
1/8 ÷ 1/6 = x
1/8 × 6/1 = x
6/8 = x
3/4 = x
0.75 = x
Answer:
<u>$239.68</u>
Step-by-step explanation:
<u>Given</u>
- Cost = $224
- Sales Tax = 7%
<u>Solving</u>
- Cost w/ Tax = Cost (1 + Tax)
- Cost w/ Tax = 224 (1 + 0.07)
- Cost w/ Tax = 224 * 1.07
- Cost w/ Tax = <u>$239.68</u>
