Answer:

$5 per shirt

Step-by-step explanation:

Set up a proportion: $\frac{8}{40} = \frac{1}{x}$
Cross multiply, then divide: 1 × 40 = 40, 40 ÷ 8 = 5
So, it is $5 per shirt.

I hope this helps!

Answer:

$5 per shirt

Step-by-step explanation:

Unit rate is price per one item so to find it you take the total cost and divide by number of items so in this case we have 8 shirts and together they are $40 we divide 40 by 8 and 40/8 is 5 that's how to get your answer.

Peter have twice as many stickers as Joe. Joe has 40 more stickers than Emily. They have 300 stickers together. How many sticker

Varvara68 [4.7K]

Answer:

170

Step-by-step explanation:

The given relations can be used to write and solve an equation for the number of stickers Peter has.

<h3>Setup</h3>

Let p represent the number of stickers Peter has. That is twice as many as Joe, so Joe has (p/2) stickers. Joe has 40 more stickers than Emily, so the number of stickers Emily has is (p/2 -40).

The total number of stickers is 300:

p +p/2 +(p/2 -40) = 300

<h3>Solution</h3>

2p = 340 . . . . . . . . . . . . . . add 40, collect terms

p = 170 . . . . . . . . . . . divide by 2

Peter has 170 stickers.

<em>Additional comment</em>

Joe has 170/2 = 85 stickers. Emily has 85-40 = 45 stickers.

We could write three equations in three unknowns. Solving those using substitution would result in substantially the same equation that we have above. Or, such a system of equations could be solved using a calculator's matrix functions, as in the attachment.

p +j +e = 300

p -2j +0e = 0

0p +j -e = 40
