Answer:

$70.77

Step-by-step explanation:

Cost of 's' yards of satin fabric= 8.09*s = 8.09s

Cost of 'c' yard of cotton fabric = 3.79 * c = 3.79c

Total cost of fabric = 8.09s + 3.79c

s = 5 yards ;  c = 8 yards

Plugin the value of s and c in expression,

8.09*5 + 3.79*8 = 40.45 + 30.32

                          = $ 70.77

What is an expression so that the product of a whole number and a decimal is 0.28
alisha [4.7K]

You may go the super easy way and choose 1 as the whole number and 0.28 as the decimal number. Then you'd obviously have 1\cdot 0.28=0.28

Otherwise, to be a bit more creative, you can observe that

0.28=\dfrac{28}{100} = \dfrac{14}{50} = \dfrac{7}{25} = 7\cdot \dfrac{1}{25}

And since 1/25=0.04, you can also choose 7 as the integer, and 0.04 as the decimal to get

7\cdot 0.04=0.28

Saravan has a bushel basket of apples to sell at his fruit stand. 2 out of every 10 cannot be sold because they are not ripe yet
tigry1 [53]

Answer:

80 percent

Step-by-step explanation:

2 out of 10  

the ten has to be turned into 100 to make it a percentage. so 10 times 10 is 100 and 2 also has to be multiplied by 10 which is 20. 100-20 is 80 which means 80 percent of his apples arent ripe.
