Adam purchased some items at the school store. He bought 3 pencils for $0.15 each and 5 single-subject notebook
If these items cost a total of $6.45, what was the cost of each notebook?
O A. $1.20
B. $1.26
O c. $1.29
OD. $1.38
Answers
Answer:
The answer is A
Step-by-step explanation:
Fist multiply 3 and .15 to get .45 for 3 pencils. Then subtract .45 from 6.45 and get 6. Then divided 6 by 5 to get 1.2 for each book
i think the answer is a: $1.20
my work:
3 x 0.15 = 0.45.
6.45 - 0.45 = 6.00
6.00 / 5 = 1.20
and i checked my work by doing 1.20 x 5 + 0.40 = $6.45.

Answers

Two negatives make a positive. So the expression 8-(-1) is equal to 9, because the two subtraction signs the equation create an addition sign, and the equation becomes 8 + 1.
Therefore, 9 has the same value as 8-(-1).

Benjamin decides to treat himself to breakfast at his favorite restaurant. He orders chocolate milk that costs \$3.25$3.25dollar sign, 3, point, 25. Then, he wants to buy as many pancakes as he can, but he wants his bill to be at most \$30$30dollar sign, 30 before tax. The restaurant only sells pancakes in stacks of 444 pancakes for \$5.50$5.50dollar sign, 5, point, 50. Let SSS represent the number of stacks of pancakes that Benjamin buys.
Answers
Answer:
4 stacks of packages
4 * 4 = 16 pieces of pancake
Step-by-step explanation:
Maximum amount to spend ≤ $30
Milk chocolate = $3.25
Pancakes per stack = 5.50 (sold in stacks of 4)
Let number of stacks = s
In equality terms :
3.25 + 5.50s ≤ 30
5.50s ≤ 30 - 3.25
5.50s ≤ 26.75
s ≤ 26.75 / 5.50
s ≤ 4.86
Hence, 4 stacks of pancakes can be purchased
Answer:
3.25+5.50S<30
Step-by-step explanation:
Benjamin can afford at most 16 pancakes
