gdp was $147, exports were $13, government purchases were $23, imports were $19, and consumption was $42. investment is $

Explanation:

Step1: Recall GDP expenditure formula

The expenditure approach to GDP is given by:
$$GDP = C + I + G + (X - M)$$
Where:

• $C$ = consumption,
• $I$ = investment,
• $G$ = government purchases,
• $X$ = exports,
• $M$ = imports.

Step2: Rearrange for investment $I$

Isolate $I$ by rearranging the formula:
$$I = GDP - C - G - (X - M)$$
This can also be rewritten as:
$$I = GDP - C - G - X + M$$

Step3: Plug in given values

Substitute $GDP=\$147$, $C=\$42$, $G=\$23$, $X=\$13$, $M=\$19$:
$$I = 147 - 42 - 23 - 13 + 19$$

Step4: Calculate the value

First compute subtraction and addition step-by-step:
$147 - 42 = 105$
$105 - 23 = 82$
$82 - 13 = 69$
$69 + 19 = 88$

Answer:

$\$88$
