Janet has three times as many dimes as nickels and twice as many quarters as nickels. if she has $5.10 in all, how many nickels, dimes, and quarters does she have? if n represents the number of nickels janet has, which of the following equations could be used to solve the problem?
a). 5n + 10n + 25n = 510
b). n + 3n + 2n = 510
c). 5n + 30n + 50n = 510

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

$3,200 x 7.25% = $3,200 x .0725 = $232 interest monthly

$232 monthly x 12 annual = $2, 784
