(5.15 pound) x (3.40 buck/pound) = <em>17.51 buck</em>
OK, so to simplify the left hand side, we need to multiply -12 and -5 to get our final exponent for j, therefore we get j^60 = j^t,so t=60 is your answer
The number would be greater. if you think about normal multiplication, when you multiply a number by 1 the number stays the same, but when you multiple the number by less then one, i.e. a fraction you get a fraction of what you had. while a number greater then one, i.e. 2, the number increases. so 1.23 is greater then one so it would increase
n + n - 0.18n
We can rewrite it as
2n - 0.18n
And if we solve it
(2 - 0.18)n = 1.82n
So the equivalente expression is B.
