Marco paid 25.00 for a meal including a 25% tip how much was the meal befor he added the tip

Let p = price of meal before tip was added.

p + 0.25p = 25.00

Solve for p.

1.25p = 25.00

p = 25.00 ÷ 1.25

p = 20

$20

step-by-step explanation:

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
