Question 1088434
<font color="black" face="times" size="3">Let's use the idea that 1 ounce is roughly 28.3495231 grams to determine how many ounces are in 168 grams.



*[Tex \Large 1 \ \text{ounce} \approx 28.3495231 \ \text{grams}]



*[Tex \Large \frac{1}{28.3495231} \ \text{ounce} \approx \frac{28.3495231}{28.3495231} \ \text{grams}]



*[Tex \Large 0.03527396 \ \text{ounces} \approx 1 \ \text{gram}]



*[Tex \Large 1 \ \text{gram} \approx 0.03527396 \ \text{ounces}]



*[Tex \Large 168*1 \ \text{gram} \approx 168*0.03527396 \ \text{ounces}]



*[Tex \Large 168 \ \text{gram} \approx 5.92602528 \ \text{ounces}]



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



Since 168 grams is roughly equal to 5.92602528 ounces, this means that we



Step 1) Get charged 55 cents for the first ounce



Step 2) Get charged 39 cents, per ounce, for the additional 5 ounces (round 5.92602528 to 6, then note how 6-1 = 5).



So following those steps above we have 55+5*39 = 250 as the total cost in cents



Divide that by 100 to convert to dollars: 250/100 = <font color=red>2.50</font> so that points to the answer being <font color=red>choice A</font></font>
