Elenna [48]
1) 10.25 x 10^9 in scientific notation is 1.025 x 10^10

2) Now you have to subtract 10.25x10^9 - 3.0x10^7

To make that you have to put both numbers with the same power of ten.

1025x10^7 - 3.0x10^7 = 1022x10^7 more pennies than half-dollars.

Free_Kalibri [48]

Answer:

$46.20

Step-by-step explanation:

We can create a proportion to find the sale on the original price. A proportion is an equation where two ratios are set equal to each other. We create two fractions using the prices and percents. If the price is discounted by 30% then we pay 70% of the price.

\frac{70}{100} =\frac{x}{66}

We begin solving by cross multiplying numerator to denominator of each fraction.

70(66)=100(x)\\4620=100x\\\frac{4620}{100}=\frac{100x}{100}  \\46.20=x
