Each cookie costs $0.75 less than the normal price. Right now if you buy 7 of them it will only cost you $2.80!

Mathematics

sasho [114]3 years ago

Answer:

$1.15

Step-by-step explanation:

Let the current price of the cookie be C whilst the normal price is c.

From the information we can deduce two equations.

Firstly, since they are $0.75 less than usual:

C+$0.75=c

Secondly, since seven cost $2.80

7C=$2.80

We can simplify this equation by dividng by 7

C=$0.40

Now combine the equations via substitution this value above into the first equation

$0.40 + $0.75= c

c= $1.15

Therefore the normal price is $1.15

A 2-column table with 5 rows. Column 1 is labeled Decimal with entries 0.1 6 repeating, 0.3 repeating, 0.5, x, 0.8 3 repeating.
Sindrei [870]

Answer:

A 2-column table with 5 rows. Column 1 is labeled Decimal with entries 0.1 6 repeating, 0.3 repeating, 0.5, x, 0.8 3 repeating. Column 2 is labeled Fraction with entries one-sixth, two-sixths, three-sixths, four-sixths, five-sixths.

Which best shows how the table can be used to determine the missing value x?

2(two-sixths) equals four-sixths, so 2(0.5) = 1, and x = 1.

4(1-sixth) equals four-sixths, so 4(0.16) = 0.64, and x = 0.64.

Three-sixths plus one-sixth equals four-sixths, so 0.5 + 0.16 = 0.6, and x = 0.6.

Five-sixths plus one-sixth equals four-sixths, so 0.83 + 0.16 = 0.99, and x = 0.9
