Yoshi is 5% taller today than she was one year ago. Her current height is 168 cm. How tall was she one year ago

2 answers:

5% of 168:
simplify 5%=1/20
1/20 of 168=8.4
so this year Yoshi is taller than last year 8.4cm
->168-8.4=159.6cm
Yoshi was 159.6cm last year

155.6 CM
I divided 168 by 100 to find 1% then i got 1.68cm then I times that by 5 to find 5% which was 8.4cm. Finally I subtracted 168 and 8.4 to get 155.6 CM
I hope that helped :)

Round to the nearest gram

Alright, so after a half-life, half of the previous number would be left. So basically,

180 g ← 0 half lives

90 g ← 1 half life

45 g ← 2 half lives

22.5 g ← 3 half lives

11.25 g ← 4 half lives

Therefore, the answer is 11.25 grams

the wholesale price for a pair of shoes is $5.50. A certain department store marks up the wholesale price by 40%. Find the price

Furkat [3]

EXPLANATION

Price of shoes = $5.50

Markup= 40%

Let's call x to the unknown final price.

The markup percentage relationship is given by the following formula:

$\text{Markup =( }\frac{Selling\text{ Price}-\text{Cost Price}}{\text{Cost Price}})\cdot100$

Replacing terms:

$\text{40}=(\frac{x-5.5}{5.5})\cdot100$

Multiplying both sides by 5.5:

$40\cdot5.5=(x-5.5)\cdot100$

Dividing both sides by 100:

$\frac{40\cdot5.5}{100}=x-5.5$

Adding 5.5 to both sides:

$(\frac{40\cdot5.5}{100})+5.5=x$

Simplifyng the fraction:

$2.2+5.5=x$

Adding numbers:

$\text{7}.7\text{ = x}$

Switching sides:

$x=7.7$

Answer: The final price of the shoes in the deparment store is $7.7
