Question

problem 10a: ari and kiri are each saving money. - ari starts with $100 in savings, and saves $5 each week - kiri starts with $40 in savings and saves $10 each week after 4 weeks, who has more money in savings?

Explanation:

Step1: Calculate Ari's total savings

Initial amount: $\$100$, weekly savings: $\$5$, weeks: 4
Total savings = $100 + (5 \times 4)$
$= 100 + 20 = 120$

Step2: Calculate Kiri's total savings

Initial amount: $\$40$, weekly savings: $\$10$, weeks: 4
Total savings = $40 + (10 \times 4)$
$= 40 + 40 = 80$

Step3: Compare the two totals

$120 > 80$

Answer:

Ari has more money in savings after 4 weeks (Ari has $\$120$, Kiri has $\$80$).
