anna bought 3 types of fruit for a fruit salad. She paid three times as much for buleberries as for pears and \$2.50 less for strawberries than for blueberries.
A) define a variable and write algebraic expressions to represent the amount she spent on each type of fruit.
B) if the total cost was \$ 13.25 how much did anna spend on each type of fruit?

A. \$X for pears.
\$3x for Blueberries.
\$(3x-2.50) For strawberries.

B. X + 3x + (3x-2.50) = \$13.25.
7x - 2.50 = 13.25
7x = 15.75

X = \$2.25.
3x = 3*2.25 = \$6.75.
3x-2.50 = 3*2.25 - 2.50 = \$4.25.
