Lisa goes to the mall one day and buys four shirts and three pairs of pants for $85.50. she returns the next day and buys three shirts and five pairs of pants for $115.00. what is the price of each shirt and each pair of pants?

the price for one shirt is $7.5

the price for one pair of pants is $18.5

Step-by-step explanation:

Let x represent the price for one shirt.

Let y represent the price for one pair of pants.

Lisa goes to the mall one day and buys four shirts and three pairs of pants for $85.50. This means that

4x + 3y = 85.5 - - - - - - - - - -1

She returns the next day and buys three shirts and five pairs of pants for $115.00. This means that

3x + 5y = 115 - - - - - - - - - - - 2

Multiplying equation 1 by b3 and equation 2 by 4, it becomes

12x + 9y = 256.5

12x + 20y = 460

Subtracting, it becomes

- 11y = - 203.5

y = - 203.5/ -11 = 18.5

Substituting y = 18.5 into equation 1, it becomes

4x + 3×18.5 = 85.5

4x + 55.5 = 85.5

4x = 85.5 - 55.5 = 30

x = 30/4 = 7.5

Shirts cost $7.50 each and pants cost $18.50 each.

Step-by-step explanation:

Let $s be the price of shirts and $p the price of pants. Therefore we have the system:

4s + 3p = 85.50

3s + 5p = 115.00

Multiply the first equation by - 3 and the second by 4:

-12s - 9p   = - 256.50

12s + 20p =  460.00       Adding these 2 equations:

11p = 203.50

p = 18.50

Now find  s:

4s + 3(18.50) = 85.50

4s = 30

s = 7.50.

step-by-step explanation:

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
