Answer:
11) to know the 20% of 70$ we need to 70÷100×20 = 14 now the sale price will ne 70-14$ = 56$
12) same 20% of 92= 92÷100×20= 18.4 $ so now original price= 92+18.4 = 110.4
13) same 40% of 30$ = 30÷100×40 = 12$ now selling price = 30-12$= 18$
Answer:
c= 1.74
Step-by-step explanation:
4520 = 3000(c)-700
4520=3000c-700
+700 +700
5220=3000c
c=1.74
to check to see if this is right you would do this:
4520=3000(1.74)-700
4520=5220-700
4520=4520
Spacing needs to be more clear instead of having a giant paragraph. you do not write math in giant paragraphs do you
Answer:
5.50x + 2y ≤ 18
Step-by-step explanation:
Romona has a total of $18 and she has to spend it on dog food.
Dry god food cost $5.50 per bag and wet dog food cost $2.00 per can.
We have to write an inequality to show the above condition.
Let the number of dry and wet dog food she buys be x and y.
The total cost of dog food must be less than $18.
Then,
5.50x + 2y ≤ 18
This is the required linear inequality.
165 -25 =140
140/7= 20.
