To find: The expression for number of calories in a fruit salad made with one apple, two peaches and one banana.

Answer to Problem 53WE

Total number of calories in fruit salad is $4p+71$ .

Given information: An apple has 29 more calories than a peach and apple has 13 fewer calories than a banana. It is given that a peach has “ p ” calories.

Calculation:

It is given that peach has “ p’’ calories.

An apple has 29 more calories than a peach.

So, we can write expression as $p+29$ .

Banana has 13 fewer calories than an apple. So, we can write expression to relate Banana and apple as

Banana= Apple +13

Now, expression for calories of apple is $p+29$ .

So, Calories of Banana= $p+29+13$

Simplify it, it is $p+42$ .

Now, salad is made using 1 apple, 2 peach and 1 banana.

So, the expression by using the corresponding expressions as

  $p+29+2p+p+42$

Simplify it,

  $4p+71$
