Q 1 - A fast food joint sells 5 boxes of chicken nuggets for $37.40. Another fast food joint sells 4 boxes of chicken fingers for $28.48. Which food has a cheaper unit price?

Answer : D

Explanation

Step 1:

Unit price of chicken nuggets = $$\frac{37.40}{5}$ = $$7.48$

Unit price of chicken fingers = $$\frac{28.48}{4}$ = $$7.12$

Step 1:

Unit price of scarves in January = $$\frac{14.70}{3}$ = $$4.90$

Unit price of scarves in March = $$\frac{23.90}{5}$ = $$4.78$

Unit price of ‘A’ seeds = $$\frac{161.40}{6}$ = $$26.90$

Unit price of ‘B’ seeds = $$\frac{129.75}{5}$ = $$25.95$

Unit price of vendor 1 books = $$\frac{39.20}{4}$ = $$9.80$

Unit price of vendor 2 books = $$\frac{52.98}{6}$ = $$8.83$

Step 2:

As $$9.80$ > $$8.83$, unit price of vendor 1 books is higher.

Step 2:

Since $$0.81$ < $$0.91$, ice company purchase is the better buy.
