Jamar used his Chase credit card to purchase groceries for $25.87, gas for $ 42.25, and a video game for $52.24 this month. How much should his payment to his credit card company be in order for him to avoid interest charges on these purchases?

$120.36

Step-by-step explanation:

The computation of the amount that should be pay to his credit card is as follows;

= Purchase of groceries + gas charges + video game

= $25.87 + $42.25 + $52.24

= $120.36

He has to pay the above amount to his credit card company to avoid the interest charges on these purchases

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.
