Eva is picking fruit at a farm. The fees are $5 for entry to the farm, $2.50 per pound of blueberries, and $2 per pound of apple

olasank [31]

Answer:

The required expression is: $y = 5 + 2.50b + 2a$

Step-by-step explanation:

Given

$Entry = \$5$

$Blueberry = \$2.50$

$Apple = \$2$

Required

Write an expression for this scenario

If 1 pound of blueberry cost $2.50

then b pounds = 2.50 * b

If 1 pound of apple cost $2

then a pounds = 2 * a

The required expression (y) is then calculated as

$y = Entry\ Fee + Blueberry = Apple$

$y = 5 + 2.50 * b + 2 * a$

$y = 5 + 2.50b + 2a$

Hence, the required expression is: $y = 5 + 2.50b + 2a$

Two trains leave towns 471 miles apart at the same time and travel toward each other. One train travels 21 miles per hour slower

nadya68 [22]

Let the slower train's velocity be x-21

Let the faster train's velocity be x

We know that the approach speed is the sum of both speeds, so x+x -21= 2x-21.

The approach rate is given by Distance/time = 471/3 = 157mpH

x+x-21=157

2x=157+21

2x=178

x=89mph

The slower train is travelling 89-21 = 68mph

The faster train is travelling 89mph.
