lys-0071 [83]

Answer: Elena spent $3.6 +x more than Tammy.

Step-by-step explanation:

Let the cost of each cherry be 'x'.

Cost of watermelon for Elena = $7.75

Cost of 5 pounds of cherries = 5x

So, Equation for Elena would be

$7.75+5x$

Cost of pineapple = $4.15

Number of pounds of cherries = 4

So, Equation for Tammy would be

$\$4.15+4x$

Now, Elena spent more than Tammy by

$(7.75+5x)-(4.15+4x)\\\\=7.75+5x-4.15-4x\\\\=3.6+x$

Hence, Elena spent $3.6 +x more than Tammy.
