Amanda [17]

Answer:

110 test

Step-by-step explanation:

Let

x ----> the number  of packet of 10 test

y ----> the total cost

we know that

The number of packet of 10 test purchase multiplied by $11 plus the enrollment fee of $30 must be equal to $151

so

The linear equation that represent this scenario is

y=11x+30

we have

y=\$151

substitute

151=11x+30

Solve for x

subtract 30 both sides

11x=151-30

11x=121

Divide by 11 both sides

x=11

The number of packets purchase was 11

To find out the number of test, multiply the number of packets by 10

11(10)=110\ test

A farm was selling 50 1/2 apples to 2 families in need of some food. 1 family got half of what the 2nd family got.

50 1/2 <u>multiplied by</u> 1/4 = 12.625

The first number (50 1/2) is 202 times greater than the second number (1/4)

Hope this helps! :'(
