Answer:
Step-by-step explanation:
Let chocolate bar = c and blow pops = b
<u>As per given we have equations below:</u>
- 5c + 8b = 23.25
- 2c + 13b = 21.55
<u>13 times the first equation minus 8 times the second to eliminate b and find c:</u>
- 13(5c + 8b) - 8(2c + 13b) = 13(23.25) - 8(21.55)
- 65c - 16c = 129.85
- 49c = 129.85
- c = 129.85/49
- c = 2.65
Each chocolate bar costs $2.65
X+y=27
x=2y
2y+y=27
y=9
x=27-y
x=27-9=18
I think it’s 5. I’m not sure
Answer:
1. $33.00
2. $48.00
3. $3.00
4. $36.40
Step-by-step explanation:
44.00 - 25% = 33 —> $33.00
80.00 - 40% = 48 —> $48.00
9.99 - 70% = 2.997 —> (round the 7 up because it's above 5) $3.00
52.00 - 30% = 36.4 —> $36.40
