1680-670=1010, which is how much Jackie saves per month.
4 years= 48 months, so multiply 1010 by 48 to get your answer.
Umm... it's 482.
1960-740=1220, which is how much he saves each month.
48 months in 4 years, so just multiply 1220 by 48 to get your answer.
What kind of hatred do you have towards anons, Titanium?
$${\frac{{\mathtt{15}}{\mathtt{\,\times\,}}{\mathtt{\pi}}}{{\mathtt{2}}}} = {\mathtt{23.561\: \!944\: \!901\: \!923\: \!449\: \!3}}$$
$${{\mathtt{3}}}^{{\mathtt{2}}} = {\mathtt{9}}$$
$${\mathtt{9}}{\mathtt{\,\times\,}}-{\mathtt{4}} = -{\mathtt{36}}$$
$${\mathtt{\,-\,}}{\mathtt{36}}{\mathtt{\,-\,}}{\mathtt{3}} = -{\mathtt{39}}$$
f(3)=-39.
Subtract both sides by 354: 2x=y-354.
Divide both sides by 2, and x=0.5y-177.
$${\mathtt{170}}{\mathtt{\,\times\,}}{\mathtt{80}}\% = {\mathtt{136}}$$
y=3x-4
y=3x+3
Both lines have the same slope but different y-intercepts, so they are parallel but not the same line. There is no solution for this system.
10^2 is 100, so just do 6.745*100.
