Grace earns $7 for each car she washes. she always saves 25$ of her weakly earnings. this week, she wants to have at least $65 in spending money. how many cars must she wash? write and solve an inequality to represent this situation

6 cars

Step-by-step explanation:

To write an inequality, write an equation using an inequality sign. She needs to make at lest $65 then the sign must be greater than to ensure to gets that much or more than it.

She starts the week with $25. Then adds $7 for each car. This value is changing and is represented with a variable, 7x.

So the equation is 25+7x > 65.

To solve, use inverse operations like solving an equation:

25+7x>65

7x>40

rounded x>6

-4

step-by-step explanation:

(-4+8)=-(4-8)=-8+4=-4

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5
