Mark invests $500 on a saving plan. The bank pays 5% interest each year on his investment. How much interest will he have after 2 years? (40 points NEED HELP WITH WORK PLS)

Sine interest formula: total = start amount x 1 + interest rate x time)

Total = 500 x (1+ 0.05 x 2)

Total = $550

Interest = 550 - 500 = $50

it's both, now can you answer my most recent question?

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
