Ok so this is the first page 1. 78 pizzas. 20% of 65 is 13. Add that to 65 and you get 78 pizzas. It is a 1.08% decrease. When you divide 65/60 you get 1.08. Im not 100% sure about this one
2. Online store=$208 and the superstore=$224 The difference is $16 so it would be cheaper to get it at the online store
3. It is $4000. For the first year you would multiply $20,000 by 5% which is 20000*.05=1000. Then multiply 1000 by 4 years to get $4,000 Instead of multiplying the 1000 by 4, multiply by 2 to get 2000. Subtract 4000-2000 to get 2000. You saved $2,000
