Task 7: The better deal
Which deal is a better buy? Explain your answer step by step. The image is given in the following above or below and no irrelevant answers and if the answer is wrong or not applicable I will report their answer.

Answer 1

Given :-

• Two boxes of Granutty Bars .
• One box has 20 bars and costs $ 3.44.
• Second box has 15 bars and costs $ 3.41 .

To Find :-

• Which deal is better .

Solution :-

$\small{\underline{\underline{\red{\tt{\purple{\leadsto } Case\:One:-}}}}}$

Cost of 20 bars of chocolate is $ 3.44 .

So , cost of 1 bar will be $\sf\dfrac{\ 3.44}{20}$ = $ 0.172

Hence cost of each bar is $ 0.172 .

______________________________________

$\small{\underline{\underline{\red{\tt{\purple{\leadsto } Case\: Two:-}}}}}$

Cost of 15 bars of chocolate is $ 3.41 .

So , cost of 1 bar will be $\sf\dfrac{\ 3.41}{15}$ = $ 0.227

Hence cost of each bar is $ 0.227 .

Now from above two cases we see that cost of 1 bar is less in the case of big box of Granutty Bars i.e. $ 0.172 .

$\boxed{\green{\pink{\dag}\bf Hence\: buying\:big\: box\:is\: profitable.}}$

Answer 2

Solution:-

Given:-

1. Large box: 20 bars for $3.44 only.
2. Smaller one: 15 bars fro $3.41 only.

To Find: Container better to buy.

Finding cost of a Bar in:-

LARGE BOX:-

20 bars = $3.44

→ 1 bar = ($ 3.44)/20

= ($ 0.344)/2

= $ 0.172

SMALL BOX:-

15 bars = $ 3.41

→ 1 bar = ($ 3.41)/15

= $ 0.227 (Approx.)

Thus,

Bar of the big box < Bar of the smaller one.

Therefore, it is better to buy the big container.
