With an 18% discount, Joan was able to save $13.23 for a coat. What was the original price of the coat?
strojnjashka [21]
Hi there!

First we need to realise that the 18% discount equals John's savings. Therefore 18% of the original price is $13.23.

When we know 18% of the price, we can also find 1% of the total price.

18% = $13.23
Divide both sides by 18.

1% = $0.735
To find the total price, which equals 100%, we know only need to multiply both sides by 100.

100% = $73.50.
Therefore, the original price for the coat is $73.50.

~ Hope this helps you!

joja [24]

Answer: The answer is (b) a ≤ 3 + 2j; j ≥ 14, a ≤ 35.

Step-by-step explanation:  Given that Anna is no more than 3 years older than 2 times Jamie’s age. Jamie is at least 14 and Anna is at most 35. We are to select the correct combination of inequalities among the given options.

Also, 'a' and 'j' are the possible ages of Anna and Jamie respectively. Therefore, according to the given information, we can write

a\leq 2j+3,\\j\geq 14,\\a\leq 35.

Thus, the correct option is (b) a ≤ 3 + 2j; j ≥ 14, a ≤ 35.
