Strawberries sell for $3.35 per pound and bananas sell for $0.80 per pound. Mrs. Mac bought some strawberries and some bananas to make smoothies for her friends. Mrs. Mac spent a total of $11.75. Write an equation to represent this situation.

Answer 1

2h + 4 = m (twice the value of Helena's age plus 4 will equal Mark's age) 3j - 6 = g (three time John's age minus 6 will equal Glenn's age) 3.35s + .80b = 11.75
