Daria made a profit of $21.00 selling lemonade. She sold her lemonade for $0.75 per cup, received a tip of $3 from a neighbor, but also had to buy each plastic cup she used for $0.10 per cup. Write an equation to represent this situation. (4 points)

equation that represent this situation is 0.65 x + 3 = 21

Step-by-step explanation:

given data

profit = $21.00

sold = $0.75

received a tip = $3

buy plastic cup = $0.10

solution

we consider here number of cups = x

so here equation will be here number of cup price of 1 cup plus tip from a neighbor equal to selling profit

x ( 0.75 - 0.10 ) + 3 = 21   1

0.65 x + 3 = 21

so equation that represent this situation is 0.65 x + 3 = 21

step-by-step explanation:

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
