Question

1. a store is offering 2 specials: 8 bracelets for $13.20 or 6 bracelets for $9. jada needs 48 bracelets for party favors. should she buy 6 orders of the 8 - bracelet special or 8 orders of the 6 - bracelet special? explain your reasoning.
2. two cars travel at a constant speed. car a travels 220 miles in 4 hours. car b travels 360 miles in 6 hours. which car is faster? explain your reasoning.

Explanation:

Problem 1 (Bracelets):

Step1: Calculate cost for 8-bracelet special

Total cost = $13.20 × 6 = $79.20

Step2: Calculate cost for 6-bracelet special

Total cost = $9 × 8 = $72

Step3: Compare costs

$72 < $79.20, so 6-bracelet special is cheaper.

Problem 2 (Cars):

Step1: Find speed of Car A

Speed = $\frac{220}{4}$ = 55 mph

Step2: Find speed of Car B

Speed = $\frac{360}{6}$ = 60 mph

Step3: Compare speeds

60 mph > 55 mph, so Car B is faster.

Answer:

Jada should buy 6 orders of the 8-bracelet special; Car B is faster.
