Answer:
Step-by-step explanation:
The original price of the math book is
50$, The amount of money that you have with you is $35.
If you get a discount of 20%, it means that you get 20% of $50. This is expressed as
20/100 × 50 = 0.2 × 50 = $10
The new cost of the math book is determined by subtracting the discount from the original price. It becomes
50 - 10 = $40
Since the amount that you have with you is $35, the amount that you need to borrow in order to buy the math book is
40 - 35 =$5
Answer: The answer would be C
Step-by-step explanation:
37 + 5 = 42
Each teacher needs 8 and there are 5 teachers

Answer:
notebook: $2.5
pen: $1.5
part B, he can buy 3 pens
Step-by-step explanation:
A
let the cost of notebook be n, cost of pen be p
1. 4n + 3p = 14.5
2. 5n + 6p = 21.5
by 1, you can get 3p = 14.5 - 4n, put it into 2
5n + 2(14.5 - 4n) = 21.5
5n + 29 - 8n = 21.5
3n = 29 - 21.5 = 7.5
n = 2.5
put n = 2.5 into 1
4(2.5) + 3p = 14.5
3p = 4.5
p = 1.5
B
Waseem buy 3 notebooks for each pen, let number of pen be m, then the number of notebook will be 3m
m(2.5) + 3m(1.5) < 27
2.5m + 4.5m = 7m < 27
m < 27/7
maximum integer value for m = 3
Answer:
Total seashells = (6g + 10) seashells.
Step-by-step explanation:
Given that Mario collected 3g seashells.
Given that Jasmine collected 10 more seashells that mario. It means she collected (3g+10) seashells.
It says to write the number of seashells they collected together in terms of g.
Total seashells = Mario's seashells + Jasmine's seashells.
Total seashells = 3g + (3g+10).
Total seashells = 6g + 10.
Hence, Total seashells = (6g + 10) seashells.
