Answer:320
Step-by-step explanation: 8 bats equals 40 grams of insect. 8 x 5= 40. 64 bats equals 320. 64 x 5 =320.
Answer:
Expression: p = 320 x 1.2
Your price: $384
Step-by-step explanation:
Finding 20% is the same as multiplying that number by 0.2 adding it on to the original number. This can also be represented as multiplying by 1.2.
This means the expression is p = 320 x 1.2, where p is the new price.
This gives you $384.
Let the number of chairs Gavin build per week is x and number of tables he builds per week is y.
It takes 4 hours to work on a chair and 10 hours to work on a table. So time taken to work on x chairs and y tables will be:

Gavin wants to work for no more than 40 hours. So we can write the inequality as:

It takes $10 worth of supplies to build a chair and $15 worth of supplies to build a table. So cost or worth of supplies for x chairs and y tables will be:

Gavin wants to spend no more than $80 on material. So we can write the inequality as:

Thus the system of inequalities is:


We can observe the possible combinations from the graph of these inequalities, which is shown below:
a) 0 chair and 3 tables
b) 5 chairs and 2 tables
c) 8 chairs and 2 tables
