Vicki, Jamal and Tyson are ordering subs from a shop that lets them choose the number of meats, cheeses and veggies that they want. Vicki chooses 1 meat, 2 cheeses and 5 veggies for
her sub and paid $5.70. Jamal paid $7.85 and got 3 meats, 2 cheeses and 2 veggies on his sub.
Tyson ordered 2 meats, 1 cheese and 4 veggies and paid $6.15 for his sub. How much would a
sub that had 4 meats, 2 cheeses and 3 veggies cost?

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
