Answer:
son = 6 mother = 48
Step-by-step explanation:
Mother = m
son = s
m = 8s
m+6 = 9/2 * (s+6)
so
2(8s + 6) = 9(s +6)
16s + 12 = 9s + 54
16s - 9s = 54 - 12
7s = 42
s = 42/7 = 6 years old
so the mother is 8s = 8*6= 48 years old
Answer:
the anwers is 5
Step-by-step explanation:
<span>The price for the three bags of chips is (3 x 2.50) - 2.50/2, because one of the bags will have 50% off. This makes $6.25. Divide this by 100 to find 1%, then multiply by 5 to find 5% — this tells you the amount of sales tax to add on. (6.25/100) x 5 = 0.31 to two decimal places. The final amount for the total purchase is 6.25 + 0.31 = $6.56.</span>
