Answer:
C
Step-by-step explanation:
First, in order to find the lowest price, you have to find the cost for 1 can in each store.
Save Rite: Since it is $ 5.25 for 3 cans, you divide 5.25 by 3. The quotient is 1.75. So, the price is $ 1.75 per can.
Then you do the same for Spend Less.
Spend Less: Since it is $ 7.50 for 5 cans, you divide 7.5 by 5. The quotient is 1.5. So, the price is $ 1.50 per can.
Since Save Rite's price for one can is $ 0.25 more than Spend Less, it is more expensive.
So in order to see how much she paid for 15 cans from the cheapest store, you would have to multiply 15 by 1.5.
The answer is 22.50.
The answer is C
9/50=x/300
you would have to cross multiply. 2,700=50x
then you want x by itself so you divide each side by 50.
x=54
Any number times 1 is the number itself so 1 times 4/7 is 4/7 and 1 times 4/5 is 4/5
Answer:
5/8 or 62.5%
Step-by-step explanation:
There are a total of 8 pairs of socks and 5 black ones, so the ratio is 5/8. We can divide this and get the percent by 5/8=0.625 and multiply by 100% which equals 62.5%.
Answer:
the scale factor is times 0.5
Explanation:
20 plus 10 is 30. Half of 20 is 10 so that is 0.5
It is also like that for the others
