Kiara spent 1/5 of her money on earrings and a neckalace. The necklace cost 3 times as the earrings. Kiara has $400. How much did kiara spend for the necklace. How much did she spend for the earrings.

Necklace = $75

Earrings = $25

Step-by-step explanation:

after spending 1/5th of total, Kiara has 400. So what's her total?

Let total money be x, so we can write:

x - 1/5x = 400

4/5 x = 400

x = 500

So Kiara spent 500 - 400 = $100 for necklace and earrings.

We know necklace cost, n, is 3 times earring, e. Thus we can say:

Necklace + Earring = 100

3 Earring + Earring = 100

4*Earring = 100

Earring = 25

Thus, necklace is 100 - 25 = 75

Kiara spent $75 for Necklace and spent $25 for the earrings.
