Question 833333
HOW TO THINK THROUGH THE PROBLEM FOR MULTIPLE CHOICE:
If she bought the same number of oranges at each price, then the average price she paid was
{{{(45^c+35^c)/2=40^c}}} per orange, so she must have bought
{{{"$ 44.00"/"$ 0.40 / orange"=110}}}{{{oranges}}} .
 
TO EXPLAIN WITH "show your work":
{{{x}}}= number of oranges bought at each price.
($0.45)x + ($0.35)x = $44.00
{{{0.44x+0.35x = 44}}}
{{{(0.44+0.35)x = 44}}}
{{{(0.80)x = 44}}}
{{{x=44/0.80}}}
{{{x=55}}}
So Jane bought a total ={{{2x=2*55=highlight(110)}}} oranges.
