Gio mows lawns for $25 each. He already has $250 in his bank account, but is trying to save $900. How many lawns will he need to mow to reach his goal?(1 point)
Gio needs to save an additional $900 - $250 = $<<900-250=650>>650.
Therefore, he will need to mow $650 / $25 = <<650/25=26>>26 lawns. Answer: \boxed{26}.
Lani buys groceries at the store for $30.25. He spent $5.25 on apples, $3.25 on a box of crackers, and the rest on 3 pounds of lunch meat. How much did the lunch meat cost, in dollars per pound?
Lani spent a total of $5.25 + $3.25 = $<<5.25+3.25=8.50>>8.50 on apples and crackers.
He spent $30.25 - $8.50 = $<<30.25-8.5=21.75>>21.75 on 3 pounds of lunch meat.
Therefore, the lunch meat cost $21.75 / 3 pounds = $<<21.75/3=7.25>>7.25 per pound. Answer: \boxed{7.25}.
Sari is creating a dog run space in her backyard. She has 40 feet of fencing to go around the outside, and she wants to make it rectangular with a width of 8 feet. What will the length be, in feet?(1 point)
The dog run will have two equal sides with a length we'll call "L" and two equal sides with a width of 8 feet.
The 40 feet of fencing will be divided between the two lengths and the two widths.
Since each length has the same length and there are two of them, this gives us 2L.
Since each width has the same length and there are two of them, this gives us 2 * 8 = 16 feet.
2L + 16 = 40
2L = 40 - 16 = 24
L = 24 / 2 = 12
Therefore, the length of the dog run will be 12 feet. Answer: \boxed{12}.
Siara is baking biscuits for a bake sale. Each batch makes 75 biscuits, and her friend gives her another 60 biscuits. She ends up with 360 biscuits total for the bake sale. Use algebra to solve for how many batches she made.
Let's assume the number of batches Siara made is "b".
Since each batch makes 75 biscuits, the total number of biscuits she made from the batches is 75b.
Her friend gives her another 60 biscuits, so the total number of biscuits she has is 75b + 60.
According to the problem, this total number is 360, so we can form the equation:
75b + 60 = 360.
Subtracting 60 from both sides of the equation:
75b = 360 - 60,
75b = 300,
b = 300 / 75,
b = 4.
Therefore, Siara made 4 batches. Answer: \boxed{4}.
Jose has a comic book collection that he keeps among 5 shelves with an equal number on each shelf. His father adds 20 comic books to the bottom shelf, so the shelf now has 125 books. How many total books are in his collection? Use algebra to solve the equation.(1 point)
Let's assume the number of comic books on each shelf before the addition is "x".
Since there are 5 shelves with an equal number of books, the total number of books on the 5 shelves before the addition is 5x.
After his father adds 20 comic books to the bottom shelf, the total number of books on that shelf is x + 20.
Therefore, the total number of books on the 5 shelves after the addition is 5x + (x + 20) = 125.
Combining like terms, we get 6x + 20 = 125.
Subtracting 20 from both sides of the equation, we have 6x = 125 - 20 = 105.
Dividing both sides by 6, we get x = 105 / 6 = 17.5.
Since we cannot have a fraction of a comic book, we know that x must be a whole number.
Therefore, there must be 18 comic books on each of the 5 shelves.
The total number of books in his collection is 5 shelves * 18 books per shelf = <<5*18=90>>90 books. Answer: \boxed{90}.
