Answer:
$103.71
Step-by-step explanation:
Take the amount of the dog food cans and multiply it by 7:
7×$1.29=$9.03
Take the new number and multiply it by 4, since we need to figure out how much he spends in 4 weeks:
$9.03×4=$36.12
Now add the cost of the bagged dog food to the cost of the 7 cans throughout the 4 weeks:
$36.12+$67.59=$103.71
Answer:
Nice what did they get?
Step-by-step explanation:
A football field is 120 yards long (100 yards playing field plus 2 end zones 10 yards each) by 53 1/3 yards wide.
1 yard = 3 feet.
120 yards x 3 feet per yard = 360 feet
53 1/3 yards x 3 = 160 feet.
The area of the football fields is 360 x 160 = 57,600 square feet.
1 bag covers 2000 square feet:
57,600 / 2,000 = 28.8 bags, round up to 29 bags are needed.
1 bag cost $27.79.
29 bags x $27.79 = $805.91 total cost.
