Matthew went shopping and bought 2 pairs of pants and one pair of shoes for $92. Michael went shopping and bought one pair of pants and 3 pairs of shoes for $161. How much does a pair of pants cost? How much does a pair of shoes cost?

 $46

Step-by-step explanation:

set shoes as S

set pants as P.

2P+S=$92   - equation 1

P+3S=$161  - equation 2

equation 2 can also be written as:

P=$161-3S

so sub equation 2 into 1

∴2($161-3S)+S=$92

$322-6S+S=$92

$230=6S-S

5S=$230

S=46

answer is more than one

step-by-step explanation:

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
