Solve the following pair of linear equation using Cross multiplication
method
2x + 3y = 46; 3x + 5y = 74

2x + 3y = 46

3x + 5y = 74

Multiply 1st equation by 3 and 2nd equation by 2:

6x + 9y = 138

6x + 10y = 148

Subtract 2nd equation to 1st equation:

=> y = 148 - 138 = 10

=> 2x + 3*10 = 46

=> 2x = 16

=> x = 8

Hope this helps!

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
