Semenov [28]

Answer:

$Total = \$5d - 2$

Step-by-step explanation:

Represent Alice with A, her friend with F and you with Y.

From the question, we have:

$A = \$d$

$F = 2 * A$ --- Twice as much Alice means 2 times Alice's earnings

$Y = F - 2$ --- 2 less than her friend

Required

Determine the total amount

$A = \$d$

Substitute $\$d$ for A in $F = 2 * A$

$F = 2 * \$d$

$F = \$2d$

Substitute $\$2d$ for F in $Y = F - 2$

$Y = \$2d - 2$

The total amount is calculated by adding the earnings of Alice, her friend and you

$Total = A + F + Y$

$Total = \$d + \$2d + \$2d - 2$

$Total = \$5d - 2$

<em>Hence, the total earnings is 5d - 2</em>
