Answer 1

$210

Explanation:

Martha has a budget for groceries, fuel, and utilities.

Let the amount of her budget = x

She spent 20% of her budget on groceries. If Martha spent $42.00 on groceries, how much is her budget?

Hence:

20% of x = $42

20/100 × x = $42

20x /100 = $42

Cross Multiply

20x = $42 × 100

x = $42 × 100/20

x = $210

Martha's budget is $210
