PLEASE HELP ME!! I HAVE TO WRITE EXPRESSIONS FOR THESE PROBLEMS BUT I DO NOT KNOW HOW TO....

Answer 1

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)
