Answer:
B
Step-by-step explanation:
280 + 5(–5) + (–42) + 2(75) + (–200)
280 - 25 - 42 + 150 - 200
280 - 67 + 150 - 200
280 - 67 - 50
213 - 50
= $163
Answer: the original price of the shorts was $25
Step-by-step explanation:
Let x represent the original price of the shorts.
The store is having a sale in which all items are reduced by 20%. This means that the amount of discount on the shorts is
20/100 × x = 0.2x
The price of the shorts would be
x - 0.2x = 0.8x
If the sales tax is 5%, then the amount of sales tax charged is
5/100 × 0.8x = 0.04x
The final cost of the shorts would be
0.8x + 0.04x = 0.84x
Including tax, Jennifer paid $21 for a pair of shorts. This means that
0.84x = 21
x = 21/0.84
x = 25
Can be expressed as y=0.55n
<span>(5 2/3+8 1/4)+9 3/4=n+18
</span><span>5 2/3+8 1/4+9 3/4=n+18
</span>5 2/3 + 18 = n + 18 | - 18
5 2/3 = n
Answer:
Step-by-step explanation:
3x^2 + 5x + 25 when x = 3
= 3(3)^2 + 5(3) + 25
= 3(9) + 15 + 25
= 27 +15 + 25
= 67
