Question 1026053
a = cost of one apple in dollars
p = cost of one pear in dollars


<font color=blue>an apple costs $ 0.33</font> is given information, so a = 0.33. The value of p is unknown


------------------------------------------------------------


"Five apples and a pear cost $ 3.93" so we can say 


5a + 1p = 3.93


plug in a = 0.33 and solve for p


------------------------------------------------------------


5a + 1p = 3.93


5*0.33 + 1p = 3.93 <font color=green>Replace every copy of 'a' with '0.33'</font>


1.65 + 1p = 3.93


1.65 + 1p - 1.65 = 3.93 - 1.65 <font color=green>Subtract 1.65 from both sides</font>


1p + 0 = 2.28


1p = 2.28


p = 2.28


Therefore, one pear costs <font color = red>$2.28</font>
