Question

Martha has a bidget for groceries etc. She spent 20% of her budget on groceries. If martha spent $42.00 on groceries how much is her budget.

THIS MATH IS CONFUSING ME

Answer 1

Martha's total budget for groceries is calculated using the proportion of the amount spent, which is $42.00 corresponding to 20% of her budget. By cross-multiplying and dividing, we find that her total budget is $210.00.

Step-by-step explanation:

To figure out Martha's budget for groceries based on the percentage she spent, we can use proportions. If Martha spent $42.00 on groceries, which represents 20% of her budget, we can set up the proportion as follows:

20% (the percentage spent on groceries) / 100% (the total budget) = $42.00 (amount spent on groceries) / B (total budget)

Now, we solve for B using cross-multiplication:

20% * B = 100% * $42.00

0.20 * B = $42.00

B = $42.00 / 0.20

B = $210.00

Hence, Martha's total budget is $210.00.
