A) The initial value is $55. Lenny bought a soda on each day for a week. so,
$55-1.75(7)=x 
b) $11,000-850(12). $11,000 is the initial value and it costs $850 each month. Mandy pays for 12 months. So we multiply the cost of one month by 12 and subtract that cost from the total amount of money.
c)$8.45-0.25(18)

Step-by-step explanation:

(2.1 * 10^8)/(4.2 * 10^2) =

= 2.1/4.2 * 10^8/10^2

= 0.5 * 10^6

= 500,000
