Answer:

<u>35 coins are "other" coins</u>

Step-by-step explanation:

72% of 125 coins were foreign.  That means 28% of the coins are not foreign ("other coins").

28% 0f 125 = 0.28*125 = 35 coins were "other" coins

You earn $250 per month from your part-time job. You are in a kayaking club that costs $20 per month, and you save at least $100
Olegator [25]

Answer:

Amounts in the intervall 130 \leq c \leq 230

Step-by-step explanation:

We will take the variables c and s, where

c = amount to spend that month

s = savings of the month.

Since each month we save at least 100, we know that

0 \leq s \leq 100

Moreover, we earn $250 per month and we spend $20 in a kayaking club, which tells us that

250=20+s+c

and so

230-s=c

By multiplying by -1, the first inequality also tells us that

-100 \leq -s \leq 0

Consequently by adding 230 to the inequality, we get that

230-100 \leq 230-s \leq 230\\\\\Rightarrow 130\leq c \leq 230

To solve this, you cross multiply, then divide. In this case, we multiply 4 and 2, then divide by 3.

4 x 2 = 8
8 / 3 = 2.66

So, x is 2.66

32% of 1600 = 512
yaroslaw [1]

Answer:

  • 64%: 1024
  • 96%: 1536
  • 132%: 2112
  • 232%: 3712

Step-by-step explanation:

<u>64% of 1600</u>

  64% of 1600 = 2 × (32% of 1600) = 2×512

  64% of 1600 = 1024

<u>96% of 1600</u>

  96% of 1600 = 3 × (32% of 1600) = 3×512

  96% of 1600 = 1536

<u>132% of 1600</u>

  132% of 1600 = (100% of 1600) + (32% of 1600) = 1600 + 512

  132% of 1600 = 2112

<u>232% of 1600</u>

  232% of 1600 = (100% of 1600) + (132% of 1600) = 1600 +2112

  232% of 1600 = 3712
