Answer:
Lisa can buy 5 pounds of tomatoes.
Step-by-step explanation:
Given that Lisa has $ 7.80 to spend on some tomatoes and a loaf of bread, and tomatoes cost $ 1.20 per pound, and a loaf of bread costs $ 1.80, to determine how many pounds of tomatoes she can buy, the following calculation must be performed:
1.20X + 1.80 = 7.80
1.20X = 7.80 - 1.80
X = 6 / 1.20
X = 5
So Lisa can buy 5 pounds of tomatoes.
a linear equation is an equation that may be put in the form where are the variables, and are the coefficients, which are often real numbers. The coefficients may be considered as parameters of the equation, and may be arbitrary expressions, provided they do not contain any of the variables.
12 x .89 = 10.68
10.68 x 5= $53.40
answer is $53.40
