Answer: 1967
Step-by-step explanation:
Ada was 15 years when her sister Ngozi was 18 years.
This means that Ngozi is older than Ada by:
= 18 - 15
= 3 years
If Ngozi is older by 3 years, this means that she must have been born 3 years earlier than Ada
If Ada was born in 1970, Ngozi was born:
= 1970 - 3
= 1967
Answer:
$4.38
Step-by-step explanation:
First, we need to find out how much the item costs with the sales tax. 4.5% is also equal to 0.045. We can multiply 14.95 by 0.045 to get the sales tax. This would end up to be 0.67275 which we can round to 0.67. We can now add 0.67 to 14.95 to get $15.62. Since we gave the cashier a $20 bill we need to subtract 20 by 15.62 to get $4.38.
