Michael is saving money to attend a ski camp in canada. the total cost of the camp is $1500. he has 785 in a savings account and plans to save $55 per week. a.)write an equation to represent this problem. b.) use the equation to find the number of weeks he will need to save. show a formal check.

The equation to represent this problem is 785 + 55x = 1500

13 weeks are needed to save

Solution:

Michael is saving money to attend a ski camp in Canada

Let "x" be the number of weeks he saves

The total cost of the camp is $1500

Total cost = $ 1500

He has 785 in a savings account and plans to save $55 per week

Amount in savings account = 785

Amount saved per week = $ 55

Therefore, we frame a equation as:

Total cost = Amount in savings account + ( number of weeks x Amount saved per week)

1500 = 785 + 55x

Thus the equation to represent this problem is 785 + 55x = 1500

B.) use the equation to find the number of weeks he will need to save

Solve the equation for "x"

785 + 55x = 1500

55x = 1500 - 785

55x = 715

x = 13

Thus 13 weeks are needed to save

Show a formal check:

Substitute x = 13 in equation

785 + 55(13) = 1500

785 + 715 = 1500

1500 = 1500

Thus the equation is correct

is there any photos or whatever?

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
