Question

A cyclist takes her bicycle on a chair lift to the top of a slope. The chairlift can safely carry 680lb. The cyclist weighs 124 lb, and the bicycle weight 32 lb. How much more weight can the chairlift cary?

Answer 1

the total weight of the cyclist and the bicycle is,

$32+124=156lb$

Let x be the additional weight

The sum of cyclist's weight and additional weight should be less than or equal to 680 lb.

$x+156\leq680lb$

Subtract 156 from both sides

$\begin{gathered} x\leq680-156 \\ x\leq524 \end{gathered}$
